Unanswered Question
Oct 22nd, 2007

Hi, we want to try the OCS 2007 integation with a Cisco 2821 using the Microsoft Mediation Server. Do anyone has the Cisco Gateway configuration or a link where i can found an example configuration to integrate the Microsoft Mediation Server with the Cisco 2821.

Best Regards and thanks in advanced,

Jose

It's not official support at MSFT yet. If you want to get this to work, you have to use AudioCodes or Dialogic gateways. There is a chance you could make a SIP trunk from CM5, but I have heard that it does not work that great. The SIP version that MSFT uses is not quite the same as the rest of the networking industries best practice. MSFT has made it work for them only and their partners. Even though SIP is supposed to by SIP standard, it's not with MSFT and the rest of the community.

MSFT says near end of 2008, it will work with Cisco gear. hopefully have full call control, etc within the SIP trunk between Mediation and CCM.

In the mean time, you have to use AudioCodes, Diaglogic or even Shout Gateways from Net.com.

Hi Jose

you have to deal with the "+" to/from OCS mediation server.

We have configured this and it works.

the config look like this:

(XX. is the prefix for number on OCS)

voice translation-rule 11

rule 1 /^\+/ //

!

voice translation-rule 12

rule 1 /^\.*/ /+/

!

voice translation-profile FROM-OCS

translate calling 11

translate called 11

!

voice translation-profile TO-OCS

translate calling 12

translate called 12

dial-peer voice 101 voip

description OCS

translation-profile incoming FROM-OCS

translation-profile outgoing TO-OCS

destination-pattern XX.

session protocol sipv2

session target ipv4:172.16.80.32

session transport tcp

incoming called-number +...

codec g711ulaw

no vad

if you debig the sip messages, you will se if it wotks, debug ccsip messages

and also dialpeer debogging to se if you hit the correct dialpeer

deb voice dialpeer inout
