I have a customer that has a qsig trunk between a callmanager 6.1 and a NOrtel option 11. The gateway is a 2800 mgcp router. Outgoing calls from the ccm go through the option 11 and out to the pstn. The wrong number/main number is showing up as the caller id on outbound calls from the CCM. Calls from the Nortel shows the correct caller id. The debug shows a difference between the ccm and option 11, which is the num plan. Option 11 shows the num plan as E164. CCM shows the num plan as unknown. Could this be the reason for the Carrier sending the main number as the caller id, instead of the DID. Debug shows the correct number being delivered from the ccm to the Nortel, but not the num plan, which is showing up as unknown. Any ideas on how to resolve this issue? Thanks in advance for any help!
