I am planning to replace Nextone SBC with FS, Later I'll also use openZAP to
communicate with TDM but this all depends how much calls it can take, or
maybe we can also do something in clustering environment ( I am not sure
about it). But thanks again and any further help will be highly appreciated.

Hi Saeed,
I just created an account to share my setup on the wiki. I will detail
all the steps for a clean install of a debian64 lenny with FS used as a
SBC (next step is to try the new LCR module  )and what I'm doing do
stress the server.
I wrote nothing at this time so please be patient, I'm waiting for my
new hardware so that I will detail as much as possible what I'll do.
For beginning I suggest you reading the start page on the wiki,
especially these pages:
-http://wiki.freeswitch.org/wiki/Getting_Started_Guide
-http://wiki.freeswitch.org/wiki/Dialplan_XML
maybe you could tell more about the linux distribution you're using so
that I can give you some pointers for sipp...
regards.

Hi Ken,
1) I'd like to use FS to hide topology, so bypass media is not possible
2) done
3) done
4) not used
5) i'm using this ins switch.xml -> <param name="loglevel"

Regarding logging, I can see in console and in the freeswitch.log that
there is still a lot of NOTICE logging, see below:

performance...
| Quote: | | Quote: | | Quote: | 1) where possible use bypass media or media proxy modes
2) mount freeswitch/db as a ram drive (if you are using voicemail with
the internal FS DBs you'll need a way to make this persistant across
reboots)
3) see the wiki for setting reasonable ulimits
4) (this is my oppinion others may vary) dont use mod_cdr_csv
5) turn off (or reduce logging) in switch.conf.xml
all of these thing can greatly improve performance.

Thanks Anthony,
the setup is like this:
sipp server ---- FS 1 ---- FS2
FS1 is the AMD CPU that has only one extension in dialplan that
bridges
9999 to FS2. 9999 is the first extension in FS2 dialplan that
plays moh,
FS2 has no CPU pbm.
FS1 is maxing out at 60 bridged calls without your option -hp.
Using -hp, I'm now able to bridge 200 concurrent calls (a great
improvement) and the system is still reactive. CPU load is high
but not
100% and as the system responds well, I think that doesn't matter.

The

I understand that FS1 server is not the best hardware platform,
and I'm
waiting for new 4 cores server for testing.
I will update those numbers when testing with the new hardware.

Are you calling the default 9999? It's not really an appropriate

On the terminating box you should set up a manual extension that is
the first one in the dial plan

Hi Saeed,
Here is a first draft of what I did to install FS on my server.
Configuration are not present, they'll be in a next release :p
http://wiki.freeswitch.org/wiki/SBC_Setup
My aim is to setup FS as a SBC, I hope this page could be a great
startup point for others. I will update regularly based on what I did.
Saeed, why are you replacing your Nextone, it's said to be one of the
best commercial SBC on the market.
regards.
Saeed Ahmed wrote:

FS is installed on Ubuntu Server.
I am planning to replace Nextone SBC with FS, Later I'll also use openZAP to
communicate with TDM but this all depends how much calls it can take, or
maybe we can also do something in clustering environment ( I am not sure
about it). But thanks again and any further help will be highly appreciated.
Kind Regards

Hi Saeed,
I just created an account to share my setup on the wiki. I will detail
all the steps for a clean install of a debian64 lenny with FS used as a
SBC (next step is to try the new LCR module )and what I'm doing do
stress the server.
I wrote nothing at this time so please be patient, I'm waiting for my
new hardware so that I will detail as much as possible what I'll do.
For beginning I suggest you reading the start page on the wiki,
especially these pages:
-http://wiki.freeswitch.org/wiki/Getting_Started_Guide
-http://wiki.freeswitch.org/wiki/Dialplan_XML
maybe you could tell more about the linux distribution you're using so
that I can give you some pointers for sipp...
regards.
rod.

Hi Ken, Jay,
thanks for pointing to proxy media, I will test.
Ken, you are right, I was brain damaged (a stupid mistake) when setting
INFO cause this kind of level could be very verbose. I'm switching to
CRIT or ERR.

Hi Ken,
1) I'd like to use FS to hide topology, so bypass media is not possible
2) done
3) done
4) not used
5) i'm using this ins switch.xml -> <param name="loglevel"
value="info"/>, if you think an other log level is more suitable.
Regarding logging, I can see in console and in the freeswitch.log that
there is still a lot of NOTICE logging, see below:

Changing codec ptime to 30. I bet you have a linksys/sipura =D
Do you have any idea where I can switch off this kind of logging. I
thought it should be in /dialplan/internal.xml, but I see that in

thanks a lot for your suggestion.

Thanks Rod,
Its really helpful contribution.
@Nextone: I don't want to say much about it, but simply I am not happy with
it, have you heard someone satisfied with NX who also owns it?
Kind Regards

Hi Saeed,
Here is a first draft of what I did to install FS on my server.
Configuration are not present, they'll be in a next release :p
http://wiki.freeswitch.org/wiki/SBC_Setup
My aim is to setup FS as a SBC, I hope this page could be a great
startup point for others. I will update regularly based on what I did.
Saeed, why are you replacing your Nextone, it's said to be one of the
best commercial SBC on the market.
regards.

Hi Saeed,
I just created an account to share my setup on the wiki. I will detail
all the steps for a clean install of a debian64 lenny with FS used as a
SBC (next step is to try the new LCR module )and what I'm doing do
stress the server.
I wrote nothing at this time so please be patient, I'm waiting for my
new hardware so that I will detail as much as possible what I'll do.
For beginning I suggest you reading the start page on the wiki,
especially these pages:
-http://wiki.freeswitch.org/wiki/Getting_Started_Guide
-http://wiki.freeswitch.org/wiki/Dialplan_XML
maybe you could tell more about the linux distribution you're using so
that I can give you some pointers for sipp...
regards.
rod.

Hi Ken, Jay,
thanks for pointing to proxy media, I will test.
Ken, you are right, I was brain damaged (a stupid mistake) when setting
INFO cause this kind of level could be very verbose. I'm switching to
CRIT or ERR.

Hi Ken,
1) I'd like to use FS to hide topology, so bypass media is not possible
2) done
3) done
4) not used
5) i'm using this ins switch.xml -> <param name="loglevel"
value="info"/>, if you think an other log level is more suitable.
Regarding logging, I can see in console and in the freeswitch.log that
there is still a lot of NOTICE logging, see below:
2009-02-02 08:33:56 [NOTICE] switch_core_session.c:960

Changing codec ptime to 30. I bet you have a linksys/sipura =D
Do you have any idea where I can switch off this kind of logging. I
thought it should be in /dialplan/internal.xml, but I see that in
internal.xml -> <param name="debug" value="0"/>
thanks a lot for your suggestion.

| Quote: | | Quote: | | Quote: | 1) where possible use bypass media or media proxy modes
2) mount freeswitch/db as a ram drive (if you are using voicemail with
the internal FS DBs you'll need a way to make this persistant across
reboots)
3) see the wiki for setting reasonable ulimits
4) (this is my oppinion others may vary) dont use mod_cdr_csv
5) turn off (or reduce logging) in switch.conf.xml
all of these thing can greatly improve performance.

Thanks Anthony,
the setup is like this:
sipp server ---- FS 1 ---- FS2
FS1 is the AMD CPU that has only one extension in dialplan that
bridges
9999 to FS2. 9999 is the first extension in FS2 dialplan that
plays moh,
FS2 has no CPU pbm.
FS1 is maxing out at 60 bridged calls without your option -hp.
Using -hp, I'm now able to bridge 200 concurrent calls (a great
improvement) and the system is still reactive. CPU load is high
but not
100% and as the system responds well, I think that doesn't matter.

I will update those numbers when testing with the new hardware.

Are you calling the default 9999? It's not really an appropriate
extension for load testing.
On the terminating box you should set up a manual extension that is
the first one in the dial plan
to play a wav file from preferably a ram disk or /tmp
If you do plan on using this in production accept nothing less

than a

Thanks rod for a quick answer,
FS is installed on Ubuntu Server.
I am planning to replace Nextone SBC with FS, Later I'll also use
openZAP to
communicate with TDM but this all depends how much calls it can take, or
maybe we can also do something in clustering environment ( I am not sure
about it). But thanks again and any further help will be highly
appreciated.

Hi Saeed,
I just created an account to share my setup on the wiki. I will detail
all the steps for a clean install of a debian64 lenny with FS used as a
SBC (next step is to try the new LCR module )and what I'm doing do
stress the server.
I wrote nothing at this time so please be patient, I'm waiting for my
new hardware so that I will detail as much as possible what I'll do.
For beginning I suggest you reading the start page on the wiki,
especially these pages:
-http://wiki.freeswitch.org/wiki/Getting_Started_Guide
-http://wiki.freeswitch.org/wiki/Dialplan_XML
maybe you could tell more about the linux distribution you're using so
that I can give you some pointers for sipp...
regards.
rod.

3) see the wiki for setting reasonable ulimits
4) (this is my oppinion others may vary) dont use mod_cdr_csv
5) turn off (or reduce logging) in switch.conf.xml
all of these thing can greatly improve performance.

Thanks Anthony,
the setup is like this:

FS1 is the AMD CPU that has only one extension in dialplan

9999 to FS2. 9999 is the first extension in FS2 dialplan that

FS2 has no CPU pbm.
FS1 is maxing out at 60 bridged calls without your option -hp.
Using -hp, I'm now able to bridge 200 concurrent calls (a

100% and as the system responds well, I think that doesn't

I understand that FS1 server is not the best hardware

I will update those numbers when testing with the new

You have 2 major things against you, single CPU and AMD, but you

Are you calling the default 9999? It's not really an appropriate

The CPU is going from 89% idle to 0% in less than 2 seconds.
I know that I don't have to expect too much from this kind of
hardware,
but it seems strange that the CPU power vanished so suddenly.

In addition to libtool, you may have issues with the latest packages of
gcc and some other tools that FS will need. In any case, it's better to
not use Intrepid at all  Use Hardy as suggested and you will be
happy.

You shouldn't have any issues. I've used Intrepid on a VM to compile and test
FreeSWITCH quite a bit and haven't run across any issues at all after
downgrading libtool.
That said I would also recommend Hardy LTS for production servers.

gcc 4.3.2 caused a segfault to appear in openzap due to over
optimization... so yes it can bite you.

Hi all,
I completed the wiki page with the comments I made in the posts:
Re: [Freeswitch-users] FreeSwitch setup as a "Dumb" SBC
I detailed how to setup mysql/kamailio/carrierroute to use the
carrierroute module of kamailio for LCR.
I wrote this page using my memory and history of the linux commands.
Maybe some things are missing and I will update as soon as I get my new
servers for reinstallation.
I have to cleanup the way it is displayed, cause it lacks some wiki rules.
If some would like to contribute, they are welcome.

rod

Hi Saeed,
I just created an account to share my setup on the wiki. I will detail
all the steps for a clean install of a debian64 lenny with FS used as a
SBC (next step is to try the new LCR module )and what I'm doing do
stress the server.
I wrote nothing at this time so please be patient, I'm waiting for my
new hardware so that I will detail as much as possible what I'll do.
For beginning I suggest you reading the start page on the wiki,
especially these pages:
-http://wiki.freeswitch.org/wiki/Getting_Started_Guide
-http://wiki.freeswitch.org/wiki/Dialplan_XML
maybe you could tell more about the linux distribution you're using so
that I can give you some pointers for sipp...
regards.

Hi Ken, Jay,
thanks for pointing to proxy media, I will test.
Ken, you are right, I was brain damaged (a stupid mistake) when setting
INFO cause this kind of level could be very verbose. I'm switching to

Hi Ken,
1) I'd like to use FS to hide topology, so bypass media is not possible
2) done
3) done
4) not used
5) i'm using this ins switch.xml -> <param name="loglevel"
value="info"/>, if you think an other log level is more suitable.
Regarding logging, I can see in console and in the freeswitch.log that
there is still a lot of NOTICE logging, see below:
2009-02-02 08:33:56 [NOTICE] switch_core_session.c:960

Changing codec ptime to 30. I bet you have a linksys/sipura =D
Do you have any idea where I can switch off this kind of logging. I
thought it should be in /dialplan/internal.xml, but I see that in
internal.xml -> <param name="debug" value="0"/>
thanks a lot for your suggestion.

2) mount freeswitch/db as a ram drive (if you are using voicemail with
the internal FS DBs you'll need a way to make this persistant across
reboots)
3) see the wiki for setting reasonable ulimits
4) (this is my oppinion others may vary) dont use mod_cdr_csv
5) turn off (or reduce logging) in switch.conf.xml
all of these thing can greatly improve performance.

Thanks Anthony,
the setup is like this:
sipp server ---- FS 1 ---- FS2
FS1 is the AMD CPU that has only one extension in dialplan that
bridges
9999 to FS2. 9999 is the first extension in FS2 dialplan that
plays moh,
FS2 has no CPU pbm.
FS1 is maxing out at 60 bridged calls without your option -hp.
Using -hp, I'm now able to bridge 200 concurrent calls (a great
improvement) and the system is still reactive. CPU load is high
but not
100% and as the system responds well, I think that doesn't matter.

Are you calling the default 9999? It's not really an appropriate

On the terminating box you should set up a manual extension that is

|
|
Hi Saaed,
thanks for encouraging.
I'm using Kamailio to get access to the carrierroute module.
Carrierroute is a module that is able to handle very large routing table
(excerpt from carrierroute page: "This modules scales up to more than a
few million users, and is able to handle more than several hundred
thousand routing table entries", Greatings to Henning Westerholt).
When I did my first test with FS, LCR module was not available and as
I'm not a programmer I had to deal with existing tools and being able to
handle a route table with approx 160 000 entries.
I'm not a programmer so I relies on SIP (which I understand better than
C or C++ :p) and the possibility to define specific header to exchange
message between FS and Kamailio at the cost of just an extra SIP invite
parsing (maybe a bad thing for very very high call per second rate)
So if you follow the setup on the wiki, FS will pass the number to
examine, and Kamailio will send the best route to use depending on
probability (for load sharing, eg: 10% on a gateway, 20% on an other and
70% on the last one) and matching longest prefix.
Then FS uses those route.
You could also update the kamailio database and then issue a "kamctl cr
reload" to load the new routing table.
Maybe this is not the best setup, but my aim is to share what I did so
that we could converge to the best solution to use FS as a SBC, that's
why I provided also some indications to optimize FS based on what I read
on the list and the wiki.
The next steps are scalability testing, maybe a php (or whatever else)
frontend to populate carrierroute table depending on the cost of many
carriers (any people willing to contribute, don't rely on me for this
 ), FS redundancy (I'd like to use LVS and some tools like sipsack to
check the SIP process, but I'm far from having done any interesting
things on that) that is lacking against commercial SBC, some scripts to
graph the number of calls... (please an SNMP module :p)
An other way to achieve LCR could be to use the new LCR module, and I
think that Ken Rice on this list can provide advices for a high
performance LCR setup.
I subscribed to this list a long time ago, and my feeling is that FS is
a great piece of software with a great community, so that I decided that
it could be great to contribute.
regards,
rod

Hi Saeed,
Here is a first draft of what I did to install FS on my server.
Configuration are not present, they'll be in a next release :p
http://wiki.freeswitch.org/wiki/SBC_Setup
My aim is to setup FS as a SBC, I hope this page could be a great
startup point for others. I will update regularly based on what I did.
Saeed, why are you replacing your Nextone, it's said to be one of the
best commercial SBC on the market.

Hi Saeed,
I just created an account to share my setup on the wiki. I will detail
all the steps for a clean install of a debian64 lenny with FS used as a
SBC (next step is to try the new LCR module )and what I'm doing do
stress the server.
I wrote nothing at this time so please be patient, I'm waiting for my
new hardware so that I will detail as much as possible what I'll do.
For beginning I suggest you reading the start page on the wiki,
especially these pages:
-http://wiki.freeswitch.org/wiki/Getting_Started_Guide
-http://wiki.freeswitch.org/wiki/Dialplan_XML
maybe you could tell more about the linux distribution you're using so
that I can give you some pointers for sipp...
regards.

Hi Ken, Jay,
thanks for pointing to proxy media, I will test.
Ken, you are right, I was brain damaged (a stupid mistake) when setting
INFO cause this kind of level could be very verbose. I'm switching to
CRIT or ERR.

Hi Ken,
1) I'd like to use FS to hide topology, so bypass media is not possible
2) done
3) done
4) not used
5) i'm using this ins switch.xml -> <param name="loglevel"
value="info"/>, if you think an other log level is more suitable.
Regarding logging, I can see in console and in the freeswitch.log that
there is still a lot of NOTICE logging, see below:

Changing codec ptime to 30. I bet you have a linksys/sipura =D
Do you have any idea where I can switch off this kind of logging. I
thought it should be in /dialplan/internal.xml, but I see that in
internal.xml -> <param name="debug" value="0"/>
thanks a lot for your suggestion.

2) mount freeswitch/db as a ram drive (if you are using voicemail with
the internal FS DBs you'll need a way to make this persistant across
reboots)
3) see the wiki for setting reasonable ulimits
4) (this is my oppinion others may vary) dont use mod_cdr_csv
5) turn off (or reduce logging) in switch.conf.xml
all of these thing can greatly improve performance.

Thanks Anthony,
the setup is like this:
sipp server ---- FS 1 ---- FS2
FS1 is the AMD CPU that has only one extension in dialplan that
bridges
9999 to FS2. 9999 is the first extension in FS2 dialplan that
plays moh,
FS2 has no CPU pbm.
FS1 is maxing out at 60 bridged calls without your option -hp.
Using -hp, I'm now able to bridge 200 concurrent calls (a great
improvement) and the system is still reactive. CPU load is high
but not
100% and as the system responds well, I think that doesn't matter.

Are you calling the default 9999? It's not really an appropriate
extension for load testing.
On the terminating box you should set up a manual extension that is
the first one in the dial plan
to play a wav file from preferably a ram disk or /tmp
If you do plan on using this in production accept nothing less

FreeSWITCH Version 1.0.trunk (11560M) Started.
Crash Protection [Disabled]
Max Sessions[1000]
Session Rate[100]
SQL [Enabled]
The test is very simple: sipp dial 9999 that matches in my
|
FS dialplan
| Quote: | and this is bridged to an other FS machine playing music on
|
hold.
| Quote: | When I launch "top" I see after 30 to 40 s that FS consumes all
the CPU
ressources (with a mean of 50-60 % before), with 80 calls.
When I set 70 calls, I have to wait 70-80 s before seeing
|
the same
| Quote: | issue.
Presence is set to false on the 2 profile.
I have the same issue with FS 1.0.2 that' s why I tried FS
|
11560.
| Quote: | When I use the FS machine as a router to test the packet per
|
second
| Quote: | performance, I'm reaching 100Mbps with 8000pps in each
|
direction (from
| Quote: | vlan 55 to vlan56) with less than 12% CPU. So that I don't think
there's
an issue with the network.
Here is an "mpstat -P ALL 1" to show you what's happening
|
suddenly
| Quote: | with
70 bridge calls:
12:31:26 CPU %user %nice %sys %iowait %irq %soft
%steal %idle intr/s
12:31:27 all 3,00 0,00 3,00 0,00 1,00 4,00
0,00 89,00 6241,00
12:31:27 0 3,00 0,00 3,00 0,00 1,00 4,00

12:31:27 CPU %user %nice %sys %iowait %irq %soft

0,00 22,22 6035,35
12:31:28 CPU %user %nice %sys %iowait %irq %soft
%steal %idle intr/s
12:31:29 all 24,75 0,00 67,33 0,00 0,99 6,93
0,00 0,00 5483,17
12:31:29 0 24,75 0,00 67,33 0,00 0,99 6,93
0,00 0,00 5483,17
The CPU is going from 89% idle to 0% in less than 2 seconds.
I know that I don't have to expect too much from this kind of
hardware,
but it seems strange that the CPU power vanished so suddenly.
Thanks a lot for the guys that have read this long mail :p
kind regards,
rod
