customer has a as5400 gateway w/ t3 and ucm 6.1. while testing incoming DID calls, some calls are failing and q931 msg shows telco release being received after as5400 sends connect.
the cause is "Invalid call reference" weird thing is some calls work fine while others fail with this msg.

P pd = 8 callref = 0x000E
Cause i = 0x80D1 - Invalid call reference value
when telco was sending in 4-digits, all calls worked. now they are sending 10-digits, as customer requested, and the above is happening.
doesn't seem to be any consistancy with dialed number, or channel, etc.
does anyone know what telco is saying and how to correct?
