calling-info pstn-to-sip issue with two SIP-trunks, CME

Hi all,


I got a Cisco CallManager Express (c2800nm-spservicesk9-mz.124-24.T3.bin), Version 7.1 with two SIP-trunks.

One to the SIP-VoIP-Provider and the other one to a third-party VoiceMail.


The SIP-registration to the VoIP-Provider needs the  "calling-info pstn-to-sip from number set <registration nr.>" under the sip-ua configuration, because the registration-nr. isn't the same as the "real" DID-nr. range.


Unfortunately, the second trunk uses this setting as well and the VoiceMail can't figure out the origin caller-id (it's checking only the from header an not

P-Preferred-Identity number).


Who has such a setup and how can it be done to set the SIP From: information only for one trunk. I use transation-rule for mapping the internal

phone-nr. to the DID-range. This change only affect to the P-Preferred-Identity number.


Thanks,

Norbert


Debug to the SIP-Provider (working fine):
