Hello,
We use Zoiper 3.8 on an iPhone 6s and 6s Plus with Sipgate as our VoIP provider.
We can call out, but we hear the other side only on the speaker at the bottom of the iPhone and the other side doesn’t hear me. When someone tries to call us it doesn’t ring and they are connected to our mailbox.
This app seams to be useless until I can fix the problems. Please help!

in iOS by (160 points)

I have exactly the same issue with Sipgate and iPhone 6, I paid £6.99 in app purchase for the G729 codec but it does not activate anything. I have tried to contact Zoiper but as I am using the free app version there is no support. So if anybody on this forum can help that would be awesome...

Any body know how I set this up to receive calls over 3G/4G ?? Or what I have to do to activate the in app purchase.....I have tried the restore purchase button etc etc..

Thanks,

Have you tried with Zoiper for iOS 3.9? It is here:

In case the issue still persist try to alter the STUN in the Network Settings menu from the account configuration.

OK, thank you! Now it works, again.

I have just updated to Zoiper 3.11 (from 3.9)  and it is not working any longer. Don't update!!!!

The error message is: Failed to create media streams (29)

Same here. Although I can make outgoing phone-calls without any issue, all incoming calls will not transport any sound
