Solved Can't conference two callers from Yealink T48G

[seantp]

I need the ability to conference in callers from my phone. 2 way calling, not start a conference bridge.
I have the latest 3CX software and a Yealink T48G

I place the first call, then I hit the conference button. It places the first call on hold and I proceed to dial the number. When I try to connect I get an error Call Failed and Temporarily unavailable.

I've done some searching for the error but none of the results I've found seem to apply. I suspect an outbound rule from what I've read, but they've all referred to older versions of 3CX.

Help!

Can you make normal outbound calls using the same number ? , if not then you probably need to setup rules https://www.3cx.com/docs/manual/sip-trunks/

Do you have PSTN or SIP lines ?. If Sip how many concurrent calls have you configured.

I have SIP. It was my bad, I had forgotten I reduced the number of channels on my SIP trunk. Looking at elastic trunks to save some money and avoid an unnecessary limit.
