CISCO TP Infrastructure in SIP only with ISDN Gateway 3241 and Lync Interco
I have a customer who plan to deploy a CISCO TP infrastructure with: MCU 53xx / VCS C (with FindMe, OCS Enhanced Collab) / TMS / ISDNGW 3241 and C series endpoints. All the video equipments will run the very last software version.
There will be a SIP TLS Trunk between VCS C and a Lync Server 2010
He wants SIP only when possible (no H.323)
I warned him about the fact the ISDNGW 3241 only support H.323 (& H.320).
Today, I don't know how the full infrastructure will work if everything is in SIP but the ISDNGW in H.323.
In details here are my main questions :
- Does VCSc support SIP TLS Interworking to H323 to make calls from Endpoints (SIP TLS) to ISDN Network ? if it does, how to dial to the Gateway ? Prefix of course but is it required to add the domain ?
- How would the booking via scheduler work when dialing out to ISDN Endpoints ?
If you wonder why I need to implement TLS in SIP it is simply because the customer wants Lync to EP calls to run over TLS. For this specifically, OCS Enhanced collaboration is installed on the VCSc (SRTP media)
