Let’s say I have a conference room of 8 users. At some point in the evening, we need to hook up with a Zoom conference.

That means hooking up that existing pool of users to a new PJSIP
channel. An admin would dial in, enter a pin, and initiate that connection.

Sounds really simple, but I’ve read:

https://wiki.asterisk.org/wiki/display/AST/ConfBridge https://wiki.asterisk.org/wiki/display/AST/Asterisk+16+Application_ConfBridge https://wiki.asterisk.org/wiki/display/AST/Asterisk+16+Configuration_app_confbridge https://wiki.asterisk.org/wiki/display/AST/Asterisk+16+Function_CONFBRIDGE
https://wiki.asterisk.org/wiki/display/AST/Asterisk+16+Function_CONFBRIDGE_INFO

Perhaps I’m not seeing the wood for the trees, but I’m not figuring it out.

I think I need to set a variable when the admin dials the pin, and then within that variable, write the name of the new PJSIP channel which the admin caused to happen.

And then join the existing channel into the conference. That’s the bit I can’t figure out.

Thanks.

Oh, and finally, when dialling the Zoom channel, I think I need to use https://wiki.asterisk.org/wiki/display/AST/Asterisk+16+Function_PJSIP_DTMF_MODE
to “PJSIP_DTMF_MODE(inband)”
because in PJSIP wizard, I’ve set “endpoint/dtmf_mode=rfc4733”
otherwise it doesn’t work with everything else. And of course, Zoom needs audible touchtone digits.

(Before anyone says “Why not use Zoom Sip Connector” – well, £39 per month for the SIP connector, or 3*10 minutes at 1p/minute (ie:30p) per month via PSTN is why!
