Hi,
I know about these. I was wondering If CRLF is supported and if it is possible
to configure sofia-SIP to use that instead of OPTIONS for NAT keep-alive.

Subject: Re: [Sofia-sip-devel] Use empty UDP instead of OPTIONS for keep-alive
Hi, I am Gilbert Lee.
There are 3 ways of keep-alive mechanism from my experience.
1. CRLF
2. OPTION
3. REGISTER
It seems to be called SIP Session Timer while sending REGISTER message again is
called SIP Expire Time.
I do not know what is best policy of SIP Session Timer for network.
Any way, is there any standard declared document in RFC?

Hi,
Is it possible to change the behavior of NAT keep-alive to send empty
or double CLRF UDP packets? The standard solution in Sofia-SIP seems to be
sending OPTIONS and that would require much traffic and a big load on the proxy
if many clients.
Best regards,
Bengt Werstén
