Was this working before? Can you please send the complete the output of isdn q931.

Thanks, Mak.

New CIPT installation and DID range. The calling NPA NXX is unreachable only from CIPT phones with new DID range. I'm wondering if the distant cellular service provider does not recognize the new DID as valid.

That is possible. But i don't see that call is getting disconnected yet (sa its not included in the debug here). 0x8AFF is basically a From a network beyond the internetworking point giving reason as unknown for disconnect.
