Linphone: could not start tls transport on port 5060, maybe this port is already used?

networking sip netstat lsof linphone

I think my better half ran into the same problem, so I installed Ubuntu (16.04) on a spare laptop and had no issue starting linphone as an admin, but could reproduce your error as a normal user. I then added the group plugdev to the normal user logged out and then back in and linphone seems to work now as it is supposed to be.

I added the group with

usermod -aG plugdev yournormalusername

as root.

update:

Probably this is because of NAT, although that might an Ekiga specific problem.

I've tried multiple clients on this machine, cannot get any SIP clients to work for me. On the same network, an Android tablet can call an IP phone, no problem, using free SIP accounts. Also, an IP phone, SPA 942, works fine with anveo. The hardphone worked fine with a free Anveo account, so I upgraded ($5/month or so?) to the paid service.

Why is linphone reporting that port 5060 is in use?

From the GUI I set NAT and entered my external IP. After switching to ipv6 the GUI showed that the registration failed.

I would prefer to use linphonec, which is the CLI. It's just for chat.

I was able to use the OnSIP web-application to call an ekiga account registered on an Android tablet on the network.
