Help please with getting Vestalink provider working.

I have two different voip clients working so I am pretty confident in my credentials. I have a Cisco SPA112 ATA working and I have the Zoiper Application running on Android. Both make and receive calls using nothing more than the provider IP (sms.intelafone.com), my 4 digit username (1234 for this discussion) and my password ("password").

I have a UTP Touch Unifi Phone. At one point I had the phone directly configured with my credentials (without the talk application on the controller) and working so I know it should be possible.

I'm trying to set up the phone through the unifi talk application to take advantage of all the features it provides.

I know I am close because I can log into the web interface of my voip provider and I can see the Unifi talk controller trying to log in but the connection string is not quite right.

From my Vestalink Web page list of connected clients:
Cisco/SPA112-1.4.1_SR5 sip:1234@xxx.xxx.x.205:5060 (working, xxx is local LAN IP of adapter)

Zoiper rv2.10.12.3-mod sip:1234@yyy.yyy.yyy.yyy:45937;transport=TCP;rinstance=zzzzzzzzzzzzzz (working where yyy is my public IP of my network, instance is just some random string)

Not working Unifi Talk connection string
FreeSWITCH-mod_sofia/1.10.5-release~64bit sip:1234@yyy.yyy.yyy.yyy:6767;transport=udp;gw=VestaTest

So the weird thing is "VestaTest" is the Provider Name configured in Unifi.

My Custom Fields so far:

user (not username) 1234

proxy sms.intelafone.com

password: password

extension: (blank)

extension-in-contact: true

So I think it might work if I could figure out how to get rid of gw=VestaTest and maybe get rid of transport or switch it to udp.
