I just started playing with linphone, using the linux command-line
I am new to sip in general, so some obvious things will still be not
obvious to me.
I have a device based on ubuntu 11.04, Natty, and some later machines with
a newer version of linphone.
The older version is 3.3.2.
The newer linphone version is 3.5.2.
Using these two versions, i tried to do a call, but in both directions,
I.E. calling from the older version/answering on the new one, or calling
from the newer version, answering on the old one, I am getting an
ortp-error-Incompatible SDP offer received in 200Ok, need to abort the
once I did "answer".
Can this be fixed with configuration?
Calling between two devices both running version 3.3.2 works correctly.
I tried compiling the latest version of linphone from source, but ran into
issues when trying to build belle-sip.
