Diversion Header problem

[andcza (Andrzej Czarnowski)]

Hello,

I have problem with blind transfer on my PBXAct. I know from provider that I need to generate diversion header in SIP but it seems that it’s not generated.

In advanced setting “Generate Diversion Headers” is on:

For extension and SIP trunk:
sendrpid=pai
trustrpid=yes

But in SIP debug to provider I can’t see field divension (there is an PAI but no divension).
Part of my SIP debug during blind transfer is as follow:

Audio is at 14208
Adding codec alaw to SDP
Adding codec g722 to SDP
Adding codec ulaw to SDP
Adding codec gsm to SDP
Adding non-codec 0x1 (telephone-event) to SDP

Where is a problem?
What should I change to generate that field in my SIP?

Current Asterisk Version: 13.29.2

Hello Andcza,

You have to configure it in extensions_custom.conf under [macro-dialout-trunk-predial-hook] context. There you can add the diversion header using REDIRECTING function.

Many thanks for info Quarea. I will check that funttion, but I think it must be a bug or mistake in configuration. It should work.

I checked on another PBXAct (version 14) with the same asterisk 13.29.2 and when I turn on “Generate Diversion Headers” in SIP I can see diversion field. In version 13 not

So I’m looking what could be wrong with my PBXAct (version 13).
Any idea?

And one more thing.
In logs I can see that dialplan is manipulating SIP HEADER as follow

[s@sub-diversion-header:1] Set(“SIP/AAAA-00000134”, “DIVERSION_REASON=no-answer”) in new stack
[s@sub-diversion-header:2] Gosub(“SIP/AAAA-00000134”, “func-set-sipheader,s,1(Diversion,tel:AAAAAAAAA;reason=no-answer;screen=no;privacy=off)”) in new stack
[s@func-set-sipheader:1] NoOp(“SIP/AAAA-00000134”, “Sip Add Header function called. Adding Diversion = tel:AAAAAAAA;reason=no-answer;screen=no;privacy=off”) in new stack
[s@func-set-sipheader:2] Set(“SIP/AAAA-00000134”, “HASH(__SIPHEADERS,Diversion)=tel:AAAAAAAA;reason=no-answer;screen=no;privacy=off”) in new stack

but some how that field is not in SIP Debug.
Strange

Best regards,
Andzca
