Bug: linphonec fails to determine local IP when no default gateway is set

Versions:
  linphone-2.0.1
  libosip2-3.0.3-2
  libeXosip2-3.0.3-3

Platform is an embedded system, only accessable in the LAN,
so there is 
no default gw defined (and necessary) in the routing table.

Having no default gateway results in below linphonec
warnings:
  DEBUG: [get_output_if] connect: Network is unreachable
  DEBUG: [get_output_if] connect: Network is unreachable
  DEBUG: [get_output_if] connect: Network is unreachable
  ortp-error-Could not find default routable ip address !

Another result is that in the SIP/SDP header contains the
loopback IP 
instead of the device IP:
  [...]
  From: <sip:root127.0.0.1>
  [...]
  Contact: <sip:root127.0.0.1:5060>
  [...]

This is independent of the contact setting in .linphonec:
  [sip]
  contact=sip:root192.168.1.33

Adding a default gw fixes this behavior.

Calls inside the LAN are still possible without gw, but the
headers are 
obviously flawed. It seems to work anyway with all tested
peers, so I'd 
consider this as a minor error.
Currently, I don't have time to track this down, so I'd
throw it over to 
the public

Hi,

You are right.
I have submitted a patch to eXosip maintainer to fix this
problem. It will be 
fixed in next eXosip2 release.
