I am still chasing a problem with using the CC-Diversion header to redirect a call back to my service provider to an Octel system hanging off their switch.

I am a Verizon Centrex customer. Inbound calls are presented to my Cisco 2620XM router via a PRI . The called party number has 5 digits. When using the SER and CC-Diversion header to redirect an unanswered call to our Octel voicemail system I repeatedly get the following:

"Cause i = 0x809C - Invalid number format (incomplete number)"

After some digging I suspect that Verizon wants me to send them more digits so they can forward the call to the correct mailbox. This is consistent with the above error. The problem is no one, did I say no one, seems to know how many digits they want.

So the question is this. How can I manipulate the "Original Called Number" value in the outbound ISDN setup message to contain more or less digits? It seems like this value is extracted from the value in the To header. Is this correct? In the ISDN messages the original called number is always the 5 digit called party number.

Thanks,Steve
