With ios14.2 don’t wok

I love this app, but don’t work with iOS 14.2, please do something, please update, is a great app.

Where is support or documentation

Enjoying the app thus far. Haven’t had a chance to use it much. Wondering about the ability to dial direct extensions inside our sip network ?

Works wonderfully !

I use this app with SipGate and Google Voice and I must say how happy I am !

I have Google Voice set up so that incoming calls are forwarded to my SipGate number. If iSip is closed, I get a push notification which allows me to answer the call. My ONLY complaint with this is that if the caller is not patient, he/she may hang up before iSip loads and answers automatically.

The push notification also shows caller ID in the form phonenumber@sipclient. It would be great if it integrated with the contacts, as this integration is limited to using the contacts app to call from within iSip.

I have read several reviews and I can tell MOST of the people complaining simply don't know how to configure it. Read the instructions people!

iSip does have room for improvement, but as it is right now, it works great for me and I'm really happy to have bought it ! I fully recommend it.

How to work in background

This is the developer, IOS4 does not support UDP running in the background.

So we still use the push notification service to receive the incoming calls in the background. With the selection of our public push server or your local private push server (if your sip server can't be reached by our public push server), you should have no problem to receive the calls when the app is in the background.

You can download the private push server vmware image from our website. Just make sure you have set up the virtual server's interface to bridge mode, so your isip can talk with the virtual server.

The IOS4 support gives you the possibility of doing VOIP calls in the background and do other work in foreground. You can also go back and continue VOIP calls after the VOIP call is interrupted by cell calls.

This app works but you need to configure it properly

I downloaded iSip and it didn't work properly; Audio was so choppy that it couldn't be used (even on the same network than our Asterisk Server). Also under some conditions and I only got one way audio. I spent a complete day doing several adjustments and debugging the protocol to check what was happening. The application is now working fine (audio is good; Not excellent, but good enough). If you are planning to use this application; You must have really good understanding of VOIP and what is happening under the hood. For example; I am not a big fan of iSIP VAD implementation, I had to turn it off. Remember to set the stun servers if you are planning to use it behind a NAT; there are a few free stun servers on the internet. PUSH did work OK to me; although I can't answer the call when receiving the notification. IMHO there is room for improvement on this app. Buy it *ONLY* if you really know SIP protocol and you are willing to spend some time to configure/debug it to make it work correctly on your enviroment.

*** Please add g729 support ***
