Calling on a T1 CAS From Cisco H.323 Gateway Or CallManager MGCP to Nortel MICS Issue PBX

I currently have a VOIP setup with an H.323 Gateway and CallManager 4.0 using MGCP using a T1 CAS E&M-Wink-Start to connect to a Nortel MICS. I have configured the T1 to use E&M Wink Start. Signalling seems to be working perfect, the only issue I have is calling from the Cisco to the Nortel.

From the Nortel MICS, I am able to seize the trunks and make calls to the call Manager. However, when I try to call from a Cisco IP phone to the Nortel MICS, it does not work. The prime set on the MICS also does not pick up so i am guessing some kind of digit forwarding is the cause of the problem. I have enabled both H.323 and MGCP on this router to determine if H.323 or MGCP is the cause. I get the same problem for both so I assume it is some kind of router setting. I don't think it is my nortel side since i have an Analog E&M setup right now and it works perfect both ways. I am guessing it is a problem with the T1 but the nortel to cisco works perfectly, just the cisco to nortel doesn't work right now.


I issue the Debug Statement on the router : debug vtsp all or debug vtsp dsl or debug voip vstp all

The only thing out of the ordinary I see is that Digits To Dial=

is blank, but the line before it is fine. I am trying to dial xtension 101, but you have to press 6101 (6 is the access code to get out)



I also have a sh voice port summary

Both the lines are seized properly

I have exhausted every single resource I have, this is the only part left in our VOIP integration setup. Any feedback you can provide will be greatly appreciated.
