I have setup a tie trunk from a cisco voice gateway to a nortel option81. I can do 4 digit dial between the 2 systems, however when trying to dial out from a cisco phone through the nortel pbx it get a "swed quip congestion" d-channel error. It appears that the outbound calls will not transfer from the tie route to an outboud route from the option81. Has anyone seen this and know how to get around it??
Its acting as if the trunks are blocked but they are not. Trunk to trunk transfer is enabled on in the customer data block.
