A little sluggish Probably not optimized for the Intel Atom CPUs in the Asus Zen Phone 2
The October 8, 2015 update made my app stop working. It will no longer connect to my PBX. It had been working well for months.
A few suggestions Could use these functions/enhancements: 1. A way to stop the GSM side from ringing while in a SIP call 2. Increase volume beyond what the phone offers, amplify the incoming/outgoing audio 3. Tasker plugin would help a lot
Perfect SIP stack Tested all features, everything is properly implemented and works with all well known equipments.
• Audio quality improvements
• Stability and performance improvements
