[Freeswitch-users] Cisco CUCM 6.1 and Freeswitch SIP trunk

Kristian,

I'm starting to see some of that pain already! It's not wasted effort though as I have removed the ubuntu packages and built freeswitch from git so I can more easily try out different modules and versions of software. Getting mod_h323 or mod_opal to compile is proving more tricky but I can tinker with that at the same time as pursuing the SIP route, which I would definitely prefer.

I will take your advice and post the question to the lists. I'm also going to raise a call with our cisco partner, we pay them enough money for support so they can earn it for a change. I will let the list know what I find out and if I get it fixed I will write something up.

Thanks yet again

David
