Man, I’m seriously disappointed! I was so excited to learn that Grandstream had a softphone app. I’ve been fighting with it for hours now and I can’t get it to connect to my UCM-6202. I have used other softphone apps and connected them successfully to the UCM, so it’s not a firewall issue.
The features look fantastic and I really would like to use this app, but . . . this isn’t my first rodeo and I can’t get it to connect. I’ve scoured the web (and this forum, of course) to look for help but haven’t found a resolution to my issue.
I’m on T-Mobile for my LTE traffic/data, if that makes any difference.
