You should never really be able to hear the difference between UDP and TCP or TLS. The fact that you can, and your struggle with latency on your old voip provider, keep me thinking of a firewall issue. The firewalls in consumer routers are notorious for doing funny and unpredictable things with SIP UDP packets. Glad you got a different provider working. I would make sure your dial plan in your phone dials immediately after 10 or 11 digits, and that any "SIP" functions of your router are disabled, but otherwise, use what works for you! Enjoy.
After Googling around a bit, I did learn that I should disable the SIP functions in the router, so I did. I have Xfinity cable in a couple of different places, and in both cases, VoIP has been a bit hit or miss. I can get TCP on voip.ms to work, but it just doesn't go through nearly as quickly as UDP does.
I do see that the Interdigit Short Timer in the Cisco phone is set to 3 seconds. There's probably no good reason to make that shorter so I'll leave it alone.
Having reported that LES.NET was proving more reliable, over the weekend my DID responded with an "out of service" message when dialed. No idea what is up with that. Come Monday, it is working again.
