SipAddHeader() not working

[Asterix]

Hello,

my SIP Trunk Provider needs the Caller ID to be transferred as P-Prefered-Identity.

To achieve this, i’ve added the following lines to extensions_custom.conf:

[macro-dialout-trunk-predial-hook]
exten => s,1,SipAddHeader(P-Preferred-Identity:sip:[email protected])
exten => s,n,MacroExit()

Asterisk shows these modification in logfiles too:

Executing [s@macro-dialout-trunk-predial-hook:1] SIPAddHeader(“PJSIP/374-0000002d”, “P-Preferred-Identity:sip:[email protected]”) in new stack
Executing [s@macro-dialout-trunk-predial-hook:2] MacroExit(“PJSIP/374-0000002d”, “”) in new stack

But when I’m tcpdumping these packets, none of the invites to sipgate do contain the p-preferred-identity:

When searching Wireshark for any packets containing the preferred identity, no results, the header wasn’t added.

I have no clue why.

You can’t use SIPAddHeader with PJSIP channels. See this thread:

Add custom SIP header to PJSIP trunk

We have provisioned the new FreePBX 13 Server and 40+ extensions. I have two trunks that are pjsip and all extensions are configured in pjsip. Our provider does not accept the *67 anonymous caller on their trunk due to billing purposes and has suggested I setup a PAI Header to set the Privacy.id flag. We have two outbound routes - one should be used when a caller prefixes *67 which is set to override the extension CID with hidden. This is not working. Has anyone been successful in getting thi…

Thanks,

I’ve tried the following:

[macro-dialout-trunk-predial-hook]
exten => s,1,Set(PJSIP_HEADER(add,P-Preferred-Identity)=sip:[email protected])
exten => s,n,MacroExit()

But it’s still not working. Anyhow, we will use our own Trunk now, making Sipgate (and the header adding) more or less needless.

Thanks for your help.

@Asterix

it’s still not working

No, you can’t add SIP headers to a pjsip channel that way. The proper method is noted in the link above.

The other solution is to switch this trunk back to a Chan-SIP connection. Then your SipAddHeader() call will actually work because it is part of the right interface stack.
