No update of calling number when transferring a call

Hello,

 

I`ve got a CUCM 9.1.2 connected via SIP Trunk to two other PBX. 

 

When I have a call between two CUCM Phones (eg. DN 2001 calls 2002) and I start a transfer from DN 2002 to 5001 (on 3rd Party PBX) the number (and name) 2002 is signalled on called phone. So far, so good, but when I then press the transfer button the calling party number 2002 is not updated on the called phone display. It seems, that the information does not come through the SIP Trunk.

 

Any idea how I can change that.

 

Regards

Juergen, We would need to see

Juergen,

 

We would need to see the SIP messaging ideally from the CallManager traces to see why the number/name is not updated.

Hi Brian, attached you can

Hi Brian,

 

attached you can find the SIP communication. The call was started from 3001 -> 3003 and then transfered from 3003 to 3786 which is located on the 3rd Party PBX.

Bcoz the contact field of

Bcoz the contact field of Ringing message from PBX is not in proper format , it does not contains ext number. It should be like this "Contact: <sip:3786@10.7.17.30:5060;transport=TCP;oc-node=101>"

If there is CUBE in between then we need to look at CUBE logs as well or if its a direct SIP trunk between CUCM and Third party PBX then you need to look at PBX side because it sending wrong information.

Thanks Manish, I`ve forwarded

Thanks Manish,

 

I`ve forwarded that to the admins of that PBX.

 

I`ve attached 3 more logs from calls to Unify PBX. One is transferring a call without pickup on Unify side, second is with pickup and third one is with direct call transfer and pickup.

 

In all 3 logs the contact field looks correct, but I can also see the transferred number. So looks for me that the failure is on Unify PBX, or?
