From Domain in outbound gateway - Call Forward

[Adrian Fretwell]

Hello, I having trouble figuring this out, may I request a little help.

I have Outbound Caller ID set in my extensions and "Caller ID in From" set in the gateway and outbound calls work just fine here is a snip of the invite going to my SIP trunk:

INVITE sip:0123456789@myprovider.co.uk SIP/2.0.
From: "01636xxxxxx" <sip:01636xxxxxx@myprovider.co.uk>;tag=Q2vZvH22ByHNQ.
To: <sip:0123456789@myprovider.co.uk>.

Now if I forward an extension to the same PSTN number and call the extension from another extension, the invite to the SIP provider looks like this:

INVITE sip:0123456789@myprovider.co.uk SIP/2.0.
From: "Adrian WP52"" <sip:202@my.fusionpbx.co.uk>;tag=1vSQe0a6eQggB.
To: <sip:0123456789@myprovider.co.uk>.

The domain in the from header is no longer my SIP provider it is the tenant domain. So instead of sending a proxy authenticate the SIP trunk just returns a 403 relay forbidden.

I can't work out how to keep the myprovider.co.uk as the domain for an outgoing call when it is forwarded from an internal extension.

Hi Adrian,

Have you solved this problem?

Hi Jeroen,
No I have not solved it, I think the issue for me is something to do with the Dial String that the call_forward.lua script puts into the extension record when a forward is set up either through the web interface or by using the *72 feature code.

Regards,
Adrian.

I have managed to push this a little further... If in the gateway, I set "Caller ID In From" to false and set "Sip CID Type" to pid. I can now get an INVITE to my sip provider that does contain the correct domain name (that of the SIP provider) and the call doesn't get rejected with a 403 Rely Forbidden.

As I have set my SIP provider account to allow me to set the CLI, the p-perferred-identity header works well and a normal outgoing call will have the correct Outbound Caller ID Number as specified in the extension.

The problem I still have is; if I divert extension 203 to my home phone number (PSTN) and call 203 from say 202, the call fails with a "436 Bad Identity-Info" error because FusionPBX is using the extensions Effective Caller ID Number as the CLI not the Outbound Caller ID Number as the CLI. Does anyone have an idea how best I should change this behaviour when call forwarding to external telephone numbers?
