Hello Everyone,

We are using Kamailio IMS (version 5.0.4). We are using Jitsi for making calls.
Our SIP clients are behind NATed network.
When clients and P-Server is configured to UDP mode, we are able to make calls sucessfully.
When clients and P-Server is configured to TCP mode, call is not getting through.

From logs I found that ACK is not being sent from P-Server to Client.

On googling i found that this is known problem.


Can anyone kindly clarify whether this problem is resolved?
Is there is work around.
Am i not setting any parameter properly?
Let us know if further information is needed.

Kindly some answer, we are newbies...  :)

Regards

GS Kumar
