Hi, i have this simple scenario IP PHONE -> LAN -> GW -> PSTN with a CUCM 7.1 BE, 2821 with a vwic2-2mft-e1 and two isdn lines connected to both e1 ports (voice).
I have configured the gateway as MGCP both e1 ports appear registered but the problem is that when i want to call through the second e1 port 0/0/1:15 the call didn't complete. It appears the error:
i = 0x82D2 - Identified channel does not exist
The funny thing is that when i move the second isdn e1 cable from the 2821 and move it to another router 2811 with a vwic-1mft-e1 (one voice port) configured as same as the other port it works fine.
So finally, i only can have one e1 port configured on the 2821 0/0/0:15 and one on the 2811 0/2/0:15. The second port on the 2821 0/0/1:15 didn´t work for outbound call but for inbound is fine.
Can anyone help me with this, thanks for your time.
