[Freeswitch-users] Briding two sip-trunks

[Brian Campbell]

Hi Ralph
 
I have done a fair bit of work hooking FreeSwitch to Microsoft Speech Server 2007..same issue...Speech Server only does SIP over TCP
 
I have documented the whole process that I went through in a 6 part blog series over at www.gotspeech.net. 
 
Part 1 of the series can be found here http://gotspeech.net/blogs/verbalinput/archive/2009/12.aspx
 
I am still getting up to speed with Lync 2010, so I dont know whether the process is the same as it was for Speech Server 2007, but hopefully the blog postings will help you out
 
Cheers

Hi there,
 
I’m trying to use FreeSwitch to connect my MS Lync (previously OCS) to a SIP-trunk. Problem is that Lync only works using TCP-based trunks, while my SIP-provider uses UDP.
I understand that by using FreeSwitch I can bridge these two protocols. 
I installed FreeSwitch on my Lync server and configured both the external (to sip-provider) and internal (to Lync) sip profiles. These both work; when i dial in from remote to a DDI on my trunk, i can see the incoming call in the FS CLI. Same goes for outgoing calls; when dialing a number from my lync-client, the FS CLI logs the call. 
 
Now, what do i config to bridge the two trunks? I don’t need any extra extensions or otherwise, all call handling is done by Lync. All calls coming in from my external sip trunk need to be forwarded to my internal sip, and all calls originating from my internal sip need to be forwarded to my external sip trunk.
 
Can someone point me in the right direction?
 
Thanks in advance ;)
 
Ralph
