[SIP Beyond VoIP] FW: STUN keep-alive

[Mihai Richard]

Hi,

I've dug a little deeper into this and discovered that there is indeed a
keep-alive mechanism in pjsua and it uses the ka_data and ka_interval data
from the pjsua_acc_config struct and I believe sipsimple is not using pjsua
and that is why I do not see those packets. With those values left to
default it sends CRLF every 15 seconds.

And for

I could disable SIP ALG on my router but this application also has to work
in networks where I can't do any setup/networks that I do not own.

When you're saying that I should implement support for OPTIONS you mean I
should do a request = Request("OPTIONS", server_uri,...) and then a
request.send()?

Thanks,
Mihai Richard
