[Linphone-developers] Different addresses for registration and SDP negotiation, why?

[Pedro Sanchez]

Hello,

I'm running linphonec on a device that has as single Ethernet interface 
but that usually has two IP addresses assigned: IP1 which is assigned 
via DHCP and an alias (eth0:1), say IP2, which is a non-routable address 
used for local connections only, when needed.

For the most part everything works well. Linphone uses IP1 for 
registration and SDP negotiation (Connection Information, c=...). But 
once in a while it happens that linphone uses IP2 in the SDP, even 
though the SIP negotiation is using IP1. Once Linphone gets into this 
state it stays there forever and has to be restarted.

Can you suggest a reason why this would happen? Can I do something, 
probably via the configuration file, to prevent linphone from ever using 
IP2?

This is currently happening with linphone 3.3.2. I am planning on moving 
to 3.4.0 soon and I wonder if you are aware of this problem having been 
addressed in this new release?

Thanks for you advise.
