Thanks Eric S! - I found this tip and corrected my issues too:

For others, maybe this will help:

Initial issues I had were
  • outgoing softphone calls would disconnect after 25 seconds

  • incoming calls would never route to the softphone


installed Bria on my iPad 2 and iPhone 4s

in the Bria setup areas, I simply had to correct the domain to match my grandstream setting found in the control panel:

correct setting: sip.voipwelcome.com:5078

I put in my extension and my BYOD generated password from the softphone page in the control panel.

Now I can make reliable outgoing calls, as well as receive incoming calls - and the quality is awesome!
