Hi all,
I have integrated Cisco CUCM with OXE through SIP External Gateway. PSTN is a PCM R2 and is connected in OXE. The below is my scenario:
CISCO phone seizes Trunk via SIP Gateway to make an external call through Alcatel PCM.
These are the scenarios.
1) When calling a local number( within city ) from CUCM, the calls are going through and can connect and speak to the other party. No Issues.
2) When calling a national number( other city ) from CUCM, the calls are going through and can connect and speak to the other party. No Issues.
3) When calling a GSM number( all providers ) from CUCM, the calls are going through and can connect and speak to the other party. No Issues.
4) When calling any number ( all providers, all scenarios ) from OXE, the calls are going through and can connect and speak to the other party. No
Issues.
5) All OXE Extension ( SIP ) are showing the individual DID number and its managed as a private calling number in the user level. No Issues
These are the problems/issues.
1) When calling an international number( IDD / other countries ) from CUCM, the calls are going NOT GOING through and CANNOT connect and speak
to the other party.
2) In ALL calls connected scenarios, the CUCM DID Numbers are NOT displayed properly ( ex. mobile calls ) as it shows the PCM Pilot Number only.
Alcatel-Lucent : OXE Rel. 11.1
Cisco : CUCM Ver. Rel. 11.5
PSTN Provider : Algeria Telecom
I am attaching the call traces for your reference.
I would really appreciate and need your valuable suggestions in this case if anyone has encountered it.
Thanks and Regards
