SIP header blank?


(Egroeg) #1

Problem: Asterisk adds the SIP header Jitsi-Conference-Room:
We are recording a PIN to ${Pin}, but the variable ${JITSI} is not being updated inside Asterisk.

Manually, can map conferences perfectly:

[root@pbx ~]# /var/lib/asterisk/agi-bin/jitsi_curling.sh 459802518

SET VARIABLE JITSI “jealouswolvescrawlcuriously”
-or-
SET VARIABLE JITSI “false”

Extension 800 in /etc/asterisk/extensions_override_freepbx.conf is this:

[ext-local]
exten => 800,1,Set(__RINGTIMER=${IF($["${DB(AMPUSER/800/ringtimer)}" > "0"]?${DB(AMPUSER/800/ringtimer)}:${RINGTIMER_DEFAULT})})
exten => 800,2,Read(Pin,"custom/jitsi")
exten => 800,3,Verbose(result is: ${Pin})
exten => 800,4,AGI(jitsi_curling.sh,${Pin})
exten => 800,5,Verbose(result is: ${JITSI})
exten => 800,6,SIPAddHeader(Jitsi-Conference-Room: ${JITSI})
exten => 800,7,Macro(exten-vm,novm,800,0,0,0)
exten => 800,8(dest),Set(__PICKUPMARK=)
exten => 800,9,Goto(${IVR_CONTEXT},return,1)
exten => 800,hint,SIP/800&Custom:DND800,CustomPresence:800

Unless your AGI is sharing the variable context with Asterisk, I wouldn’t expect this to work. You need to make sure the JITSI variable is actually passed back to the parent process for this to work correctly, just like function calls anywhere.
