Connection between 3CX and ASTERISK

[eroe33]

Good morning
I ask for help, we have a configuration with 2 control units, a 3CX and an ASTERISK
we should interconnect them to make their respective extensions communicate
however on the ASTERISK control unit we must use PJSIP as a type of TRUNK
so here the problem arises
using the additional SIP mode with BRIDGE on the 3CX side rises correctly (but we cannot use it for corporate policies)
so I wanted to establish the BRIDGE with the ASTERISK and the TRUNK PJSIP, but I don't find how to do it
or if you have any other suggestions, not with BRIDGE but with GENERIC TRUNK on the 3CX side
thank you

Here is an old way from 3cx to make the connection https://web.archive.org/web/20161213151353/http://www.3cx.com/docs/bridging-asterisk-pbx/

thanks, i already find that, but in my case on ASTERISK i only use PJSIP.
In the link, use normal SIP

Unfortunately, using a bridge trunk to something other than another 3CX PBX is no longer supported. Probably too many related trouble tickets. The advantage of a Bridge trunk is that you could have another PBX register to 3CX, something most other PBXs are able do. It is a lot more difficult to get another PBX to allow a (generic) SIP trunk to register to it.
