Hello Folks,
we have CUCM 9.1 with SIP trunks to cisco 2951 connected to the PSTN either by BRI or PRI module.
we have implemented internal full e.164 (including +) dialplan
when we do an outgoing call (via SIP trunk and 2951) the phones first shows the full e.164 number i.e. +4970366431002. As soon as the call goes out to the PSTN, the display changes to the number format in which the 2951 sends the call to the ISDN.
Because in ISDN there is no +, the gateway translates the called number to (in this example) 70366431002 TON national. and sends this back to CUCM in the Session progress Remote-Party-ID value (see output from debug on the 2951 below)
how can we prevend that the phone is showing this number instead of the original number?
thanks a lot - mat
