Hi All,<br>
<br>
I have set up Kamailio 3.3 on Ubuntu machine.I created two user test 1 and test 2.<br>
I could use Presence and also i was able to register to Kamailio server and exchange presence status with each other.<br>
<br>
Details- I used TCP protocol .<br>
<br>
testing methods - Linphone, a sample application.<br>
<br>
I am able to register succesfully with (TCP) on to kamailio server using Lin phone and sample application.<br>
I am able to update presence status of the users.<br>
<br>
Issue :<br>
<br>
When i try to send messages between two users ( using TCP )<br>
<br>
1. from Sample application, when i try to send message, i get 420 temporarily Unavailable error from server.<br>
2. from Lin phone 3.5.2, i was able to send messages ( sue TCP) but when the other user try to reply back , i get same error<br>
<br>
480 Temporarily Unavailable. error from server.<br>
<br>
I want a support to understand why i get error while sending messages with TCP via Kamailio server.<br>
<br>
I am able to succeesfully send and receive messages when i use UDP from my sample application and Lin phone.<br>
</blockquote></div></div>
if the phones are behind nat, be sure the tcp connection lifetime is higher than the registration expire and that you don't set connection close after forward/reply. Look at core cookbook for the appropriate tcp parameter and config functions.<br>
<br>
Cheers,<br>
