Groundwire: VoIP SIP Softphone users say on Google Play
Version 5.5.4 For System Call Integration, incoming calls have no outgoing audio from mic. This is an intermittent issue.
I'm using this app with a private network, and it works flawlessly. But there is one behavior I wish I could change, and I haven't figured out how: The app keeps resetting the audio to speaker on every call. I always use a Bluetooth headset, and if I select it, it works -- for THAT call. I have to keep selecting it, and it's a bother. I'd like to set the Bluetooth as the default, and stay that way until I change it. I need that to give 5 stars. I've searched and can't find it.
App seems full featured and the functionality is fine. I have occasional lockups with the app, especially when the battery is nearly drained. Feature and function-wise, the app gets 4 or 5 stars. The flip side is the battery use. If allowed to run in the background, the phone will burn through the battery. Further work on reducing the battery usage would be extremely helpful. That said, if you can get by with setting the app to not run in the background, you should be fine.
Outgoing Call Redirection should allow one to select Sim1 or Sim2. The app needs to support dual sim phones better.
I purchased this app and use it with VoIP.ms service. I can't receive calls. The PUSH notification pops up and it then rejects the call right away. Zoiper free version works out of the box. I purchased this app because of the PUSH notification feature. Also switching to standard non PUSH doesn't work for me either. Please help to get my incoming call to work or provide a refund.
