ConfBridge dialplan_exec configuration not working as expected

jhoppe · January 30, 2021, 4:38pm

I have two channels in a ConfBridge. When one of them presses 9, I want to have them exit the conference room, place a dial, then connect and talk. Once they hang up, the caller should automatically get put back into the conference room.

ConfBridge.conf

[amtelco-conference-menu]
type=menu
9=dialplan_exec(nway-invite,9,1)
8=leave_conference

The issue is that once the caller connects to the call (Answer) the call flow continues in the dialplan and puts the channel back in the conference room right away. I am using the ‘g’ option in the Dial application, however, if I didn’t, the channel would still get placed back in the conference room right away.

I expect that the dialplan flow would stop when a call gets connected. Then once a channel hangs up, the dialplan execution would continue and end and then eventually place the channel back in the conference room.

If this is a bug in Asterisk, or something that the conference bridge menu is unable to do by design, is there any other design suggestions I can do to solve my goal? Or is there any suggestions on what I can try in order to resolve.

Thanks
Jeff

You’d need to show what the dialplan actually does.

Let me know if this is enough or what else I need to send. Thanks.

It’s likely the use of Dial() in the dialplan. You’re still in the conference bridge fundamentally, even if you’re executing dialplan. Since you can’t be in two bridges at once the bridge that Dial() creates for the call likely fails when the channel attempts to join. I believe this has come up a few times in the past on the forum, I do not recall what (if anything) people did instead.

This is how I got it to do what I needed it to do. dialplan_exec(context,exten,priority) runs dialplan applications in the realm of the confbridge as jColp mentions above. However, “leave_conference” will leave the realm of the confbridge and continue the dialplan execution. Therefore, when I want to invite another party to the conference call, I will “leave_conference”, run dialplan to Dial() and then put back into the conference room (using features.conf to channel redirect the 3rd party and Goto() in the dialplan to put the agent back in the conference room). Finally, when I want the agent to leave the conference room for good, with original caller and 3rd party by themselves, I do a dialplan_exec() that just hangs up the agent channel.
