On my Windows XP PC I have two ethernet cards with IPs: 192.168.1.10 and 
192.168.7.70

I (A-side) call to [email protected] (B-side). Route table has rule to 
send packets through 192.168.7.70.

SIP� INVITE sends from 192.168.7.70 and SIP negotiation looks FINE but in 
INVITE/SDP connection field
contains 192.168.1.10

and side B of call will send RTP to 192.168.1.10 which isn't accessable from 
B-side.
in this case B-side will listen A-side but A-side wouldn't listen B-side.

It will be nice when SDP part will contain proper connection line with IP which 
LinPhone uses to communicate with B-side.

In this case LinPhone sends everything from 192.168.7.70 but in SDP it points 
RTP to 192.168.1.10 (this is wrong)

in attachment I placed network dump gathered by WireShark
