[asterisk-users] How can I connect an existing Confbridge to a new SIP channel when DIALEDPEERNAME is empty?

[Jonathan H]

Would really appreciate some help here - into day 4 of trying to bridge a
PJSIP call to an existing confbridge.

There's a fair amount of dialplan and log to show which doesn't really work
well via plain text email, so I've taken it over to the forum at
https://community.asterisk.org/t/bridging-an-existing-conference-to-a-new-call/76806/7

Many thanks in advance.
