Re: [Linphone-developers] wrong local address and proxies and routes

[Simon Morlat]

Hello,

Somebody else from myzel.net asked me the same questions, here is what I 
answered:

Unfortunately because of lack of support from the eXosip2 sip stack, linphone 
can only have one ip address in the from, contact, and via fields of the sip 
messages. This IP address is determined by retrieving the local address that 
can connect to the internet.
Fortunately I made some recent improvements in 3.0.0 version, so that linphone 
does a double registration: the second register has contact guessed from the 
rport and received parameters set by the proxy in the first REGISTER's 
response.
So bug 1 is fixed.
For the second one, I don't understand how linphone could use a different 
address in registers and in invites. A log file would help.
