Option to change the UDP keep alive interval

[GoogleCodeExporter]

20090104-01 version -- downloaded from cydia

I'm running asterisk server 1.6 at my home. I'm using siphon to connect to
the server. The siphon registers and I get a connected message at the top
right corner.

But I see that every 15seconds, a UDP message is send from the phone to the
server of 2bytes. Then, there is an exchange happens after every 4 messages
(that is after 1 min). This 15 second message transfer is really killing
the battery life when I'm running siphon in foreground or background.

Is there anyway to customize or increase this interval ?

Thanks
Mudit

In all cases, SIP client must keep the open connection between him and server. 
Like
that it can receive the call. Otherwise if the connection is down, the server 
can't
send INVITE message.

If you want to get Siphon in background, I believe that you want to receive 
calls,
isn't it?

Certainly, it's possible to increase the interval. But the WiFi connection stay
open/active, and the battery life will be killing too.

I don't know if there are a good solution for that.

Moreover if Apple refuses the applications in background, it is for that.

The problem is whether its foreground or background, siphon still takes too 
much CPU
and resources which depletes the battery very fast. Even if I've my phone in 
sleep
mode with siphon running in background (wifi disabled, mail disabled, ssh 
disabled,
etc etc), I don't get more 3-4 hours of standby time. I think siphon should act 
more
like the Phone application which really sips power. Otherwise I may only want 
to want
to run siphon to make calls but not receive them.

BTW, thanks a ton for a great app. I was using Truphone with hacks earlier but 
that
was horrible .. 80% cpu usage. This is so much better.

It's possible ;-)

/**

 * The keep-alive transmission will be sent to the registrar's address,
 * after successful registration.

 * Default: 15 (seconds)
