[reSIProcate] KeepAlive with iptel.org

Hi,

I am facing a strange behavior with KeepAlive.

1. I set the KeepAlive Manager into DUM and then enable it with 20 sec.
timeout using setKeepAliveTimeForDatagram().
2. After registration, 4 byte UDP payloads keeps going at 20 sec. interval.
3. Next, I disable KeepAlive by setting timeout value with 0 sec. using same
function. The UDP payloads immediately stops.
4. I set timeout value back to 20 sec. to enable keepalive (and here's the
difference)
        - with iptel.org as proxy, the UDP payload does not go.
        - with another SIP proxy within the LAN, it works fine. The UDP
payloads are going fine.

I am totally baffled with this behavior. I tried another way by setting and
un-setting the keepalive manager for enabling/disabling keepalive
respectively to same effect.

Has anyone also observed this kind of behavior ??

Regards,
Nilay
