<br>I encountered few problems using Nokia's UDP implementation when there are NATs around so I would recommend you to use TCP. Maybe recent versions have solved this issue but you can find older implementations on the field...
<br>Regarding reliability and batery life I would say TCP is more reliable by itself and you will avoid UDP's retransmissions which can safe some batery if the server does not respond fast or there's a problem in the link.

Hi,<br>I came accros one Nokia-S60 Guideline regarding SIP setting in the<br>NAT/Firewall traversal section which say:"It is recommended to use TCP<br>as the transport instead of UDP since even doubled battery life can be
<br>achieved with a UI always connected to a SIP service".<br>I need OPenSER users to comment on this since what i know is that UDP is<br>more reliable transportation.<br>WBR<br>lu.<br><br><br>_______________________________________________
