Calling Party No Display in SIP Trunk

[gpsriramdc]

Hi All,

We are integrating the CUCM & CME via SIP trunk where we facing the problem in Caller ID.

In CUCM & CME we have 4 digit extension. It will transformed to 8 digit Enterprise number while calling from/to cucm & cme. Once the call answered it displays the 4 digit extension of called party instead of 8 digit enterprise no.

Hope it's updating the Phone caller Id based on "P-Asserted Identity" in SIP messages . My requirements is it should display 8 digit no & Name.

Flow :   Phone --> CUCM --> SIP Trunk --> CME --> Phone.

Any Suggestions !!!

do you have 'no remote-party-id' under SIP-UA in CME?

Thanks suresh . It's working. But it will affect the internal SIP phones cme also.

Has there anyway to apply this specific to dial peer ?

[Suresh Subramanian]

I don't think no other commands under dial-peer.

but what exactly it is affecting on the CME SIP phones?

Hi Suresh !

Regretting for delayed reply. When i made a call from CME SIP Phone (7821)calling party no just displayed as "9" but actual dialed is 9XXXXXXXX.

SCCP Phone (7911) working fine without issue.

Thanks in Advance...

Hi All,

I just tried with SIP Profiles on the dial peer to remove the Remote-party ID.

When call initiated from CME to CUCM , "Remote Party Id"  is removed in Invite. When CUCM reply with 180 ringing it contains "Remote Party Id" but sip profile not having any effect.

This to avoid the displaying CUCM internal number series in CME instead of DID.

Can you advice how it can be achieve ?

Configuration

!

voice class sip-profiles 10
request ANY sip-header Remote-Party_ID remove

Call Flow

Thanks in Advance
