[SR-Users] Regarding Instant messaging using TCP on Kamailio 3.3

[Sunil Chandrasekharan]

Hi All,

I tested again today by disabling the presence module.

Still i could not make TCP based IM working with Kamailio.

I checked the tcp-connection-lifetime =3605.
Still i get 480 Temperory un available.

Step 1 : login/register on two lin phones ( on differnt PC)
Step 2: from PC 1 (user A) send message to user B
Step 3: user B receive the mesage.
Step 4. Send message from User B to User A

Result : 480 Temperory unavailable.

1. I feel user A connection is getting closed . Hence not able to reach
user A.

2. I also see User A and User B message contruct has 2 Via headers.

There is no change or anything abnormal happening.

Kindly help me forward to get tcp based IM working between two clients.
