Hi Guys,
I have client with a Cisco 2690 call manager solution that wants to upgrade
but cannot stomach the costs of continuing with Cisco

The installation will go up to 100 users
The client currently has about 40 Cisco phones and would like to continue
with these phones with the odd Polycom

I'm looking at plugging in an Asterisk box and using the existing Cisco box
as a PSTN gateway only

Has anyone on the list done this?
Any pitfalls or tips you would like to share?
Thanks

Femi

Hi Femi

We have about 50 Cisco 7960s on one site off Asterisk 1.4.18

Its all SIP and it doesn't stress a P3 system much at all.

I am not sure what phones you are using - the 7960s are not hard to configure, a bit of process to convert from the Cisco Skinny to
SIP (using SIP v8.6) but everything seems to work well. The 7961s or 7971s use an XML config which is probably

Everything loads off the TFTP server. We are using the Linksys POE Switches SFE2000P which seem okay but don't always like to be
fully loaded

Things I would work on are automating or simplifying the provisioning (doesn't change that much once its done), firmware upgrades,
and getting to know the config files well.

Cheers Duncan

Basic process:

1) Build the A*k server so that it has tftp installed (or another box
that does)
2) Build up the SIPdefault.conf and get the firmware files in place (see
Cisco docs on this, plus theres loads on the wikis).
3) Test with a single phone, change its tftp server to the asterisk.
Check that :

a) The firmware switches to SIP
b) the phone registers to A*k and all is well. Calls can be made etc...

4) Once your happy with the A*k config and I mean ***really*** happy,
then add in all the configs for the other phones (I used scripts to
build mine).
5) Try a few more phones manually. But eventually just update DHCP so
that the tftp server option points to the A*k server.
