incoming call T1 Pri fall

[jtroncoso]

Hi

I have a 2901 with 4 Pri T1 >connected to a CUCM 8.5 >and a 8.5 UCCX

when agents answer calls after a while this fall

how awesome is that the issue is random. on the router there are no errors in CO

and the only mistake was caught Cause i = 0x80FF - Interworking error; unspecified.

if anyone can help us be very grateful

Disconnect/error comes from telco, so you have to ask them why.
