Re: [Freeswitch-users] No ACK for 200 OK

5 Jun 2018

      Dear Michael Jerris,

Thank you for your consideration!

sofia loglevel tport 9
Sofia log level for component [tport] has been set to [9]

Here is the log when the parameter in the gateway was commented out

In the received packet in the header Contact:
<sip:1000@[2a02:7b43:1eb0:eb21::2]:5060;transport=udp>
the selected transport is udp!!! Freeswitch does not sent ACK
As for tport log I do not see any fatal errors in this case, maybe you, as
a specialist, can see?
