Great app, but needs bring up to 2019 standards

Been using it since March 2010 and still use it today. It works and works very well. I have multiple numbers and works flawlessly with them all. My only complaint is the inability to block numbers, I get numerous spam/harassing calls and it would be a useful feature. Please do it I’m sure it would give your app the edge.

Edit: Thanks for the reply. I can see it has Callkit but rejected calls still show as missed calls in Softphone and trigger the badge notification. Any way of fixing this?

Thank you for your review. Acrobits Softphone has CallKit integration and it honours the iOS system-level block list. If you need more powerful features, like rule-base call rejection, you may want to check out our business-caliber SIP app: Groundwire

Absolutely brilliant.

I have never paid for a software sip phone before, but after reading the good reviews I decided to give it a go. I am glad I did I can finally receive incoming calls even if the phone is asleep provided the provider supports push notifications. You have the option in the menu of testing push notifications to make sure it works. Very pleased.

This is possibly the best designed ‘Softphone’ on the market. Made with attention to detail, works seamlessly. The handoff to Bluetooth AirPods and Carkit works well. Visual feedback during the call is great, helps clarify if you have bad signal. Keep up the great work.
