Hello Asterisk users



Server: Asterisk 11.7.0~dfsg-1ubuntu1 on Raspberry
Client: Zoiper on Android device

If "Transport=tcp" everything works fine, without any trouble.

If "Transport=tls" registration is fine. But after a few minutes, the
peer continuously is "reachable...unreachable".

The same happen with two other devices. TCP is fine, TLS is not.

As a test, I configured two accounts on the same device with identical
parameters, except one is TLS and the other is TCP. The result is the
same: TCP is fine, TLS is intermittent.

Any idea?


Thanks for any hint
