[asterisk-users] PJSIP add header not working

[Bryant Zimmerman]

Andre
  
 For this to work we have had to go to using the b() option in the dial 
legs for the calls that are pasting up.
 You call a context that gets run before the calls are made on each 
channel. This allows you to add headers to the new pjsip channels. 
 It works well. You can also set variables with the _ option to trigger 
which headers you want to add..
  
 The example below would add "ThisHeader", "ThatHeader" and "Call-Info" to 
the new channel created in the dial. You could use combinations of other 
variables and augment these methods to meet almost any need. 
  
 Exp
  
 [OutboundDial]
 exten => _XXXXXXXXXX,1,NoOp(Dial Exp)
 exten => _XXXXXXXXXX,n,Set(_var1setinparrent=1) ;;Set Variable so that 
when you call the b() option context in your dial the first header is 
added
 exten => _XXXXXXXXXX,n,Set(_var2setinparrent=1) ;;Set Variable so that 
when you call the b() option context in your dial the second header is 
added
   exten => _XXXXXXXXXX,n,Set(_varAddSessionInparrent=1) ;;Set Variable so 
that when you call the b() option context in your dial the second header is 
added

 exten => 
_XXXXXXXXXX,n,Dial(pjsip/3332224444 at vendortrunk,b(AddpjsipHeaders^s^1))
  
  
 [AddpjsipHeaders]
  exten =>s,1,Gosubif({"$[var1setinparrent}}"="1"]?ThisHeader,1)

 exten =>s,n,Gosubif({"$[var2setinparrent}}"="1"]?ThatHeader,1)
 exten 
=>s,n,Gosubif({"$[varAddSessionInparrent}}"="1"]?addSessionCallInfo,1)
  
 exten => ThisHeader,1,Set(PJSIP_HEADER(add,ThisHeader)=ValueToSet)
 exten => ThisHeader,n,Return()
  
 exten =>  ThatHeader,1,Set(PJSIP_HEADER(add,ThatHeader)=ValuetoSet)
 exten =>  ThatHeader,n,Return()
  
 exten => 
addSessionCallInfo,1,Set(PJSIP_HEADER(add,Call-Info)=<sip://127.0.0.1>\;answ
er-after=0)
exten => addSessionCallInfo,n,Return()
  
 Thanks

Subject: [asterisk-users] PJSIP add header not working   

Hi,
I am trying to add a custom header to my calls to map several call-legs 
into a global call for viewing.

For this to work I read the call-id from pjsip-channel and write it into 
X-CID:

######

Set("PJSIP/10-00000006",

    -- Executing [s at macro-dialout-trunk-predial-hook:5]

But I can't see that header anywhere in my call-legs. What am I missing?

kind regards,
