Any help is appreciated. I am using 3CX with a virtualpbx account. I got it all setup, and the system is registering. I also set up the incoming call on the virtualpbx side, and when I call my VOIP number, the android rings. Great. However, outgoing calls fail. The screen shows on hook, but after dialing nothing happens. No sound, no ring tone. Nothing. Then after a short wait it returns to "on hook". When I call the voip number, the phone rings, and I can answer, but then dead again. Nothing. Any help?
