[Linphone-developers] bug in belle-sip 1.6.3 or linphone 3.13

[John Hughes]

(yes I know it's a very old version of linphone, I'm on Debian :))

In order for the people in my small company to work from home during 
France's COVID-19 lockdown I've configured linphone to talk to our 
existing asterisk system.

It's working well but I was shocked to see that linphone was burning up 
20% cpu time while idle.

What is happening is that linphone send a SIP REGISTER but when it gets 
back a SIP OK it refuses to believe that it matches so it resends the 
SIP REGISTER, rinse and repeat.

The problem is that nobody seems to be setting the public_ip field.   It 
should be set by belle_sip_channel_set_public_ip_port, which is called 
from belle_sip_channel_learn_public_ip_port which is called from 
belle_sip_channel_message_ready, called from acquire_body_simple, or 
acquire_chuncked_body, or belle_sip_channel_parse_stream.

I'm pretty sure belle_sip_channel_parse_stream is being called at 
appropriate places so I'm going to have to find out why it's not working.

This is Debian bug
