 Please make sure that  Zoiper is allowed to use the microphone on your device.
Open iPhone's "Settings"->"Privacy".

If the microphone is enabled, but still there is one-way audio, or no audio at all, please try to disable or enable STUN according to its current state. "STUN" is located in Zoiper -> "Settings"->"Accounts"->your account->"Network Settings".

If using Zoiper with WiFi, please make sure that the routing device is not blocking ports used by Zoiper. The default ports used by Zoiper are:

SIP port is 5060
IAX port is 4569 UDP
RTP port is 8000 and above UDP

Default STUN vallues:
Server hostname /IP :stun.zoiper.com
Port : 3478 UDP/TCP
Refresh period : 30

Still not working on my iPhone 6s with wifi or 4g. 

Not able to change the STUN for sip gate either. 


I have a similar problem, but cannot change anything in the account settings on my iPhone as all options are grey. I have used a provider profile during account setup. 

Can anyone help?



Hi. I tried everything but nothing changed. When I see statistics, incoming packets are zero.
