Cisco CallManager 4.1.3 sr6a with Codian/Tandberg ISDN Gateway

Hello everyone,

I am running CCM 4.1.3 sr6a and I am trying to integrate a Codian/Tandberg ISDN gateway to CCM and I running into this weird issue, hope someone can help !!

- The Codian/Tandberg ISDN gateway itself has a built-in auto attendant and I've configured the ISDN gateway in CCM as an H.323 gateway and I can dial to the AA on the ISDN gateway by dialing a 4-digit extension from my video enabled phone but for some reason I am not getting the audio stream from the AA when dialing by 4-digit extension. But if I dial by IP address from a Tandberg video endpoint by passing CCM then it works, I get both video and audio streams. So I am suspecting there is something that is not right during call setup when CCM is involved.

Any suggestions / inputs is highly appreciated !!! Thank you all very much in advance !!!
