Just a thought. Are you using the voip ATA on the Fritzbox and the 2talk app on the iphone. If so you need to login to your 2talk account and click on locate me/one number on the inbound calls column. Once on that page you need to tick Enable '2talk One Number' feature on this line. After doing that go into the settings on your iphone app and where you have your phone number put a -1 on the end eg 0x xxxxxxx-1. Without that your Fritzbox and iphone app will be competing for your phone number and causing one another to disconnect. That is if you haven't already done this.

Oops my bad I just read that you are using your iphone only. The only other suggestion I can make is to try other VOIP apps there are probably a few around in the Apple store.

Is there an app you can recommend. I just updated my 2Connect to the latest version dec. 2015.

Thanks

Yes the one that I use is Adore softphone. They have an app for iphone android and windows phones. When it asks you for a sip server you just put sip.2talk.co.nz then its just your phone number and password.

Thank you so much. I will keep 2talk connect. 

After having more problems with my 2talk phone connection to my Fritzbox. I have now downloaded the free Fritzbox app to my iphone 5S and magic it is working!!!  No echo, always ringing, no dropping calls.
