SBC SIP INVITE Message - From Header Field does not contain SBC's Signalling IP

Netmart
Level 1
Level 1

Hello,

For some reason SBC does send within INVITE message the IP Address of SIP Client [private IP] instead of

SBC signalling IP.

 

Example:

Client SIP Host IP: 192.168.58.1

SBC Outside SIP Signalling IP: 199.150.1.1

Adjacency Peer IP: 166.34.245.231

 

Via: SIP/2.0/UDP 1199.150.1.1
From: “3660110” <sip:3660110@192.168.58.1>;tag=199.150.1.1+1+56c....
To: <sip:1201123456987@166.34.245.231;user=phone;phone-context=unknow

 

Desired SIP Invite From Field

 

From: “3660110” <sip:3660110@199.150.1.1>;tag=199.150.1.1+1+56c....

Put this command in your outgoing dialpeer

voice-class sip requri-passing

Hello Mohammed,

Thank you for response. We are not using dial-peers.

Therefore, I am not able to apply it.

 

I try to explain the situation:

 

SIP Client  is sending call through SBC to another carrier.

For call identification reasons, we had to apply a customized method profile for this adjacency.

I am wondering, if this could be the cause for the SIP INVITE From Field issue, where instead of the SBC's outside signalling IP, the SIP Server's private IP is passed.

Please see example, the FROM field should contain SBC's Signalling IP and not any information about the

SIP Client Private IP, which is initiating the calls.

 

Currently:
From: sip:+12125551212@192.168.80.1;tag=887s

Desired:
From: sip:+12125551212@<SBC Outside Signalling IP>;tag=887s

Could this be because you have this enabled?

"header-name From passthrough"

 

By default the SBC should include its own IP in the host portion of the From header.

Header name from passthrough would be causing it

Correct, removing this parameter fixed it.

 

Thanks.
