Hello,

I have the following problem: Every call stops after 30 seconds when TLS
is enabled. SIP/RTP and SIP/SRTP works but not TLS/SRTP.
The phones are behind NAT. So I expect, that every 30 seconds an Options
request is sent.

Wiresharking the traffic I can see

* that there are ongoing UDP packets.
* Then a TSLv1 packet ist sent from FS to the Phone.
* This is acknowleged by the phone
* Next the phone send another UDP packet to the same FS port as before
* Then the Phone receives an ICMP request that the FS port is closed.


Anybody has a clue about this?

Best regards
Peter

Some additions:
TLS/RTP instead of SRTP does also not work.
There are no logs on the debug console except the message that the call
is being terminated

If its TLS you don't need options packets in the first place. Your
client should do the keep alive NOT FreeSWITCH. TLS is over TCP and
Options over UDP... doesn't make much sense.

Hello Brian,

ok, I got it. Any other idea why the UDP port is closed after the TLS
packet?

Best regards
Peter
