Hi all,

I know that freeswitch has not been designed as a pure sip
proxy/registrar, but I'm wondering how many subscribers could be handled
by FS.

I setup the following test environment:
- Kamailio 1.4.2 as the registrar
- all invite requests are flowing through FS, even for a call
between 2 registered subscribers. Many reasons for this: the calls CDR
are centralized in the same format, I can easily add a billing ID to a
call, proceed to recording, set the caller as anonymous if requested...
- FS is used also as a SBC

There is still a lot of work to do, mainly on the call forwarding
feature and this is why I'm wondering (simply out of curiosity) what
could have been achieved using only FS (easier to setup when only one
equipment is involved ).

I'd like to register 40 000 subscribers (if each user registers every
60s, you have approx 670 registration per second, this setup is working
on Kamailio).

I did the following to increase FS performance regarding registration:
- put the directory containing users in a RAMDISK
- put the db directory in a RAMDISK

with this I was able to reach 190 registration per second (50 without
the ramdisk) but for one SIP account, not too useful :p (for your
information I see a huge improvement when switching from 1.0.1 phoenix:
150cps to FS svn 105xx: 190)
When trying with 25000 SIP accounts, I got no more than 30cps.

Then I tried to use the odbc mysql for registration, using this I was
able to achieve 50cps. The mysql DB is not in a RAMDISK. For all these
tests, the presence support has been disabled.

As the IO performance seems to be a bottleneck, I'd like to know if
there is a way to store the registration in memory only without database
persistency.

This thread is there only to share tips, not to complain about FS poor
performance as a SIP registrar when compared to Kamailio. If I compare
FS to a commercial SBC I'm using in production, I have to say that FS is
really a great piece of software (lacks only statistics module, snmp,
and heartbeat redundancy for failover).

regards,
rod

You actually have potentially ~1320 effective "SIP transactions" per
second to support 40000 registered ua's with a 60s refresh. This is
because the ua sends it's registration refresh unauthenticated. The
registrar will then push back an authentication challenge request so the
ua can prove its identity, at which point the ua then repeats the same
transaction, but with authentication credentials attached.

Hi David,

very happy to read you on the FS list!

We met in 2001 at OSCon San Diego, where you "infected" me with the
telephony virus .

You did great work with the Bayonne project, really breaking new ground.

Thank you,

happy hacking,

happy new year!!!!



Sincerely,

Giovanni Maruzzelli

Yes, it is part of the SIP specs.
BTW, also HTTP works the same way.

What revision of FreeSWITCH are you trying with? I would try with
current trunk, I have a suspicion we fixed the main issue your running
into.

If your not using sqlite, make sure to create indexes on the tables
created, you should be able to grep the ones we do in sqlite out of
the code.

Well, there are worse virus's one could be infected with, I suppose .

Actually recently I had been surviving focusing on secure VoIP and
wireless...
