I am using Wifi.KerryG said:Using Wifi or 3G? 3G has a lot of issues with voip calls.
I am using it with a VOIP provider (callcentric and ipkall). I tried using this app with a newer phone (Galaxy S II) and an older phone (HTC Wildfire) ; it worked fine with those phones except my Galaxy SL.leejor said:Are you using this with 3CX PBX, or a VoIP provider?
Next release of 3CX or a new firmware for the phone :?:leejor said:It sounds then, like an issue (setting/option/incompatibility?) with that one particular phone. Unless someone is using the same model, and has a solution, you may be out of luck until, perhaps, the next release.
