Hello all,
I’m receiving an a-leg that’s in a ringing state.
Then I’m receiving another leg (b-leg) which i’m answering and parking.
This b-leg at some point sends a reINVITE, that triggers a lua (via execute_on_sip_reinvite) which tried to bridge the 2 legs.
Event though it seems to work, both legs are hung up immediately, both with ORIGINATOR_CANCEL.
I’ve tried:
-
Answering A-Leg
-
Execute on B-Leg an intercept to A-leg
-
NOT Answering A-Leg
-
Execute on B-Leg an intercept to A-leg
-
Answering A-Leg
-
Execute on A-Leg an intercept to B-leg (with -bleg)
-
NOT Answering A-Leg
-
Execute on A-Leg an intercept to B-leg (with -bleg)
-
Answering A-Leg
-
Execute on B-Leg: uud_bridge B-Leg A-Leg
-NOT Answering A-Leg
- Execute on A-Leg: uud_bridge B-Leg A-Leg
nothing seems to work…
Any ideas?
Thanks!
answer a leg and park, then from bleg intercept aleg.
Hello @dujinfang
Many thanks for the reply, but that’s not working.
The legs seem to be bridged but fs hangs up immediately.
The dialplan executed on the reINVITE (which is when i want to bridge the leg to the A-Leg):
<action application="set" data="hangup_after_bridge=false"/>
<action application="set" data="api_res_answer=${uuid_answer ${a_leg}}"/>
<action application="set" data="api_res_park=${uuid_park ${a_leg}}"/>
<action application="intercept" data="${a_leg}"/>
console output:
[DEBUG] switch_ivr_bridge.c:2213 (sofia/intercept/13153860607@dev.tncp.textnow.com) State Change CS_EXECUTE -> CS_HIBERNATE
[DEBUG] switch_ivr_bridge.c:2215 (sofia/legacy/16313643986@dev.tncp.textnow.com) State Change CS_PARK -> CS_HIBERNATE
[NOTICE] switch_ivr_bridge.c:2335 Hangup sofia/legacy/17053007553@dev.tncp.textnow.com [CS_CONSUME_MEDIA] [PICKED_OFF]
First leg is hung up with “ORIGINATOR_CANCEL” and the second leg with NORMAL_CLEARING…
Any help is appreciated!

Can you also show the dialplan of the a-leg, if it did answer, it should not show as originator cancel.
Also a full log with SIP (sofia global siptrace on) is helpful.
Hello and thansk!

Bleg dialplan:
<extension name="intercept">
<condition field="destination_number" expression="^intercept_([0-9a-fA-F]{8}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{12})$">

</extension>
The lua script triggered on reINVITE is simply:
init()
my_leg_uuid = session:getVariable(“uuid”)
a_leg_uuid = api:executeString(“uuid_getvar " … my_leg_uuid … " destination_number”):gsub(“^intercept_”,“”)
session:setVariable(“a_leg”,a_leg_uuid)
session:execute(“transfer”,“answer_” … a_leg_uuid);
and the transferred to extension is:
<extension name="intercept_answer">
<condition field="destination_number" expression="^answer_([0-9a-fA-F]{8}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{12})$">
<action application="set" data="api_res_setvar=${uuid_broadcast ${a_leg} hangup_after_bridge true}"/>
<actoin application="log" data="ERR api_res: ${api_res}"/>
<action application="set" data="hangup_after_bridge=false"/>
<action application="set" data="api_res_answer=${uuid_answer ${a_leg}}"/>
<action application="log" data="ERR api_res_answer=${api_res_answer}"/>
<action application="set" data="api_res_park=${uuid_park ${a_leg}}"/>
<action application="log" data="ERR api_res_park=${api_res_park}"/>
<action application="intercept" data="-bleg ${a_leg}"/>
</condition>
</extension>
There’s a limit of 2000 chars
So, because the first leg (call it A-leg) was being bridged with another leg and ringing, what end up working was:
- Transfer the A-leg to an extension than answered it + park it
- Then intercept from B-leg to A-leg
Thanks for the help!
