Gigaset and 3cx did anyone connect them with SRTP?

Question

Asterisk

Given:
1) 8 Gigaset c610a ip phones
2) PBX 3CX
Task:
1) Configure SRTP, TLS
2) from 4 simultaneous calls.
We tried, and it did not work for us:
1) grandstream gxw-4008 gateway (1 simultaneous call)
2) Uploading a certificate to the phone database (unstable operation)
Can anyone try to do this through "asterisk"?

Answer 1

Look at the version of Asterisk (3cx seems to be based on it)
There are some difficulties with TLS:
