I am having good success so far with Grandstream Wave softphone.
How to configure:
set up a dummy account such as 1.1.1.1 with name like "test"
sip userid anything such as your call sign.
use checkmark in upper right to save account settings.
disable random ports
disable use # as dial key
when dialing a call use * for . and # for :
ignore all other settings.
You must have a SIM card in the iphone.
This has driven me partially crazy but I think that solves my problems.
Still awaiting arrival of more SIM cards from Verizon to test all my iphones.
I do not understand why a SIM card is needed, but it has made 2 of my iphones work.
I don't know what brand of SIM card is needed, but I am assuming if they are all the same that will work.
I assume the phone may need to be "unlocked". No sure exactly what that means.
I have discussed all this extensively with both Apple and Grandstream support people, and none of them
really understand it.
