It is possible to use pjsip to connect to a 3CX Phone System over the 3CX tunnel?

Hello All, Hope All doing good.

I will split the question in some sub questions:

Is the 3CX tunnel a true TCP SIP proxy?
It is possible to use the pjsip to connect to it?
How should I set up the account and connection data if this is possible?
Let's consider the 3CX server is running behind the NAT and the public IP address is: 123.123.123.123, tunnel is working on port 5090 and the internal address of the 3CX is 192.168.1.13. the SIP user is [email protected] with pass: userPass and the tunnel has the password tunnelPass.

How should the pjsip account structure be initialized?

I very much doubt you will be able to connect to the 3CX tunnel except using 3CX applications, 3CX own protocol.
