I have a strange issue when starting linphone, it tells me :
"Could not start TCP transport on port 5060, maybe this port is already used."
I do not have any other service listening on port 5060 (see below)
$ netstat -ltupn | grep 5060
udp 0 0 0.0.0.0:5060 0.0.0.0:* 8858/linphone
I am using linphone 3.4.2, freshly compiled from sources
Is there a configuration hint I could do to correct that ?
