[asterisk-bugs] [JIRA] (ASTERISK-24536) AMI redirect with PJSIP fails to move extra channel

Mark Michelson commented on ASTERISK-24536:
-------------------------------------------

I have not been able to reproduce this problem yet. Here is my test extensions.conf file:

{panel: title=extensions.conf}
{noformat: nopanel=true}
[default]
exten => _2xx,1,NoOp()
same => n, Dial(PJSIP/${EXTEN},,tT)

exten => 306,1,Answer()
same => n,Playback(demo-congrats)
same => n,Hangup()
{noformat}
{panel}

I place a call from PJSIP/200 to PJSIP/201 by dialing 201. I have the "tT" in the Dial() to force a basic bridge since that's what appears in your logs. I then issue a redirect like the following:

{noformat}
action: redirect
channel: PJSIP/200-00000000
exten: 306
context: default
priority: 1
extrachannel: PJSIP/201-00000001
extraexten: 306
extracontext: default
extrapriority: 1
{noformat}

Both phones are succesfully redirected to {{306 at default}}. I've tried the test about 20 times and it has been successful every time. I suspect there is either a difference in
A) The way that you are establishing the initial bridge. I use the Dial() application. Are you doing it some other way? Originate? The Bridge() application? Since you filled in the choice that this issue happens constantly, I suspect that this may be where our setups differ.
B) The load on the system. When I run my test, it's the only call in the entire Asterisk system. I suspect that if there is a race condition, and you're using a more heavily-loaded system, you may see the issue more frequently than me. However, that would not necessarily contribute towards the issue happening constantly.

> We have one softmix with one or two PJSIP channels in. Then we are sending an AMI action:

> extracontext: hold-bridge
> extrapriority: 1

> Result: the first channel is placed in hold-bridge,moh,1 but the second is hunged up.
