SIP Transport, UDP Only?

Post by bilaliz »

I am trying to config fpl to use as my primary line on my iphone via Bria/Siphon/GroundWire etc, the problem is that all those apps eat up ALOT of battery about 70% down in 4 hours with any of the apps. the work around is to use TCP instead of UDP. but it seems like FPL dosnt support TCP yet? is there any way to get it working, or a new feature request is needed.

When i jumped into this i convinced a lot of my friends to follow my lead once i got it up and running. but the battery thing is a killer. ...
so to summarize do we have TCP or TLS? can we get it? how soon?

TCP is not a standard way to transport SIP packets. UDP for SIP VOIP is industry standard. Even if you used TCP, that would not solve your problem, the issue is with SIP VOIP over NAT itself.

The reason why you are eating a lot of battery is that SIP needs to send keep alive packets every 2 minutes to make sure the NAT device does not forget where to route the incoming calls. Thus your radio has to be on all the time. That is what is killing your battery.

we definitely need to work on a process to make this less battery/data consuming
