[reSIProcate] Sending "Keep alives"
Hi,
In debugging my SIP phone, I can connect just fine and have an audio
conversation, then it will stop in about a minute or so.
Further investigation indicates my SIP stack is not sending keep
alive packets.
I fired up TCPDump, and sure enough, I'm not sending any keep
alives to the SIP server. What could be the reason? I obviously
suspect I'm not setting it up properly.
My what mechanism do I make sure Keep alives are sent about every
5 secs or so. Does the SIP stack do this automatically, or do I
have to implement a timer to do this myself? I presume the
keep alive is a simple header and carriage return, right?
Is there a resip function or method that allows me to control
this? It appears I haven't setup my SIP stack properly, because
it isn't sending them.
Thanx
John
