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 you point to the pages you found that show it is a known problem to see what is there about?

If the client is not keeping the connection open, kamailio cannot connect to a device behind nat -- this could be a reason. Otherwise, run with debug=3 and look at log messages to see if there is something that can give you hints about what happens.

Cheers,
Daniel

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
