SIP trunk - username caller ID

[saifuddin.miyaji]

Hi,

I have following senario:

IP Phone(3400)---> CME--->Internet----->SIP Proxy

SIP Proxy Server: xyz.com

SIP Username: xuser

SIP Password: password

While the call is being send to the SIP Proxy, is looks like this:

INVITE sip:009123232323@xyz.com:5060 SIP/2.0

Via: SIP/2.0/UDP 91.140.172.32:5060;branch=z9hG4bK92D1AF1

Remote-Party-ID: "xuser" <sip:3400@91.140.52.20>;party=calling;screen=no;privacy=off

From: "xuser" <sip:3400@xyz.com>;tag=E796DD60-1FA6

To: <sip:00912923232323@xyz.com>

Next rejects the call because of the 404- Not found message:

------------------------------------------------------------------------------------------------------

SIP/2.0 404 Not Found
Via: SIP/2.0/UDP 91.140.52.20:5060;rport=57925;branch=z9hG4bK92D1AF1
From: "xuser" <sip:3400@xyz.com>;tag=E796DD60-1FA6
To: <sip:009129623232323@xyz.com>;tag=as4ddaa55f
Call-ID: DEFDA60D-4E8511E2-8F86B5C9-5A38862F@91.140.52.320

I believe that the issue here is that CME is sending the phone callerid as SIP user name. Actually, the invite message should like this:

From: "xuser" <sip:xuser@xyz.com>

Could someone please advise, how to force CME to do this?

Regards

Saif

There can be another reason. Beside, sending calling number is correct. Ask first why the call is rejected.

Paolo,

The reason for call rejection is very clear from the logs. username "3400" is unknown to proxy server and so it sends error 404 - user not found.

Are you sure the called number actually could be reach?

Yes, the called number is absolutely reachable. When used the same credentials on a SIP client like Xlite, it dial the number very well and everything looks good there.
