When I get a chance this afternoon I may configure one and see if that at least resolves the issue, though I didn't think I needed STUN for this particular use case.
So I haven't totally found root cause but it appears to be an issue with my windows profile on the machine I was running Linphone on.
I installed Linphone app on my phone and everything worked perfectly.
Installed desktop app on a spare laptop and everything worked perfectly.
Logged in as different user on original machine and everything worked perfectly.
Logged back in as myself on original machine and no go.
I only need this for some testing. Once we get set up we'll be using Yealink phones so I may not look anymore since I can use my phone for the testing.
Thanks to all for the help.
