do a debug isdn q931 and/or a debug voip ccapi inout to verify if the telco is the one sending the call or if this is related to CUCM



if this helps, please rate

Are you using a T1 CAS or T1 PRI or perhaps something else?

As recommended try a debug voice ccapi inout and a debug h245 asn1 and debug h225 asn1 and upload the output.
