Hello everyone, I am having an issue with out Nortel 81c switch that has been ongoing for a few months now. The issue is with one of our DSN PRI trunks. When there is an incoming call on DSN it works for all extensions in the range of 2000-2999 but when an incoming call is made to extension 1000-1999 the calls are being rejected. I monitored the D Channel and this is the message I am receiving when an incoming call is made:
DCH 40 UIPE_IMSG CC_SETUP_IND REF 000008E2 TOD 13:10:26 CK 7927D8D1
CALLED #:1*** NUM PLAN: UNKNOWN TON: UNKNOWN
CALLING #:2352*** NUM PLAN: UNKNOWN TON: UNKNOWN
PRECLEVEL: #4 - RTN

DCH 40 UIPE_IMSG CC_RELEASE_CONF REF 000005BA CH 40 23 TOD 13:10:26 7927DA

I have been working with our provider and the 1000s and 2000s are being routed the same. I am wondering if there is an issue with how our switch is translating 1000 extensions. Any help would be greatly appreciated.
