We've got a CallManager 4.2 implementation and have been having some issues. We are working on slowly moving away from our old Opt 81c to Cisco VoIP. Right now we are still using our PBX to handle all our incoming calls. This is the way it?s setup.
Opt 81c <---> 2851 2-QSIG T1?s <---> CallManager
The 2851 is setup as an MGCP gateway.
Everything seems to be working and setup ok except we?ve run into a few issues here and there, the biggest on being voice mail. We have Call Pilot integrated with Nortel and it has worked for the most part.
When calling someone with a VoIP phone, you hear their external greeting. If you leave a message and they check it, they hear 91 + the 4 digit extension as the calling number. Also, if you try to login using just the # it doesn?t work unless you add 91xxxx (xxxx being their extension) to the login information in call pilot. I?ve checked everything I know and we have our PBX support personnel looking at it as well.
I was doing some debugging and noticed something interesting. When I call from VoIP to the PBX, this is what I get on debug isdn q931.
Calling Party Number i = 0x0081, '4451'
Called Party Number i = 0x80, '7393'
When I call the other direction?
Progress Ind i = 0x8183 - Origination address is non-ISDN
Calling Party Number i = 0x4980, '7393'
Called Party Number i = 0xC9, '4451'
It concerned me that the VoIP to PBX call didn?t have the Plan or Type information filled in.
Any help would be greatly appreciated!
