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?

Developer Response ,

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.

Well worth the money

I have used this with Sipgate for 6 months and have to say it works very well, without any noticeable battery drain. Voice quality is not always fantastic but could be a weak mobile signal. Overall it is good value for money and easy to use.
