Are you using SIP or IAX2?
Does the issue appear on both 3G and WiFi?
Does the issue appear with each of the available codecs?

If you are using SIP account, please try to enable or disable STUN in account configuration -> "Network Settings".

Do you use TCP or UDP? Please try using TCP if your provider supports it.
You might want to try changing the audio driver in Zoiper -> Config -> Audio settings.

Hello,

Please try selecting a different driver form "Configuration" -> "Audio" -> "Audio Driver" and test to see if there is improvement in the quality.

Also if you experience lack of audio or one-way audio due to NAT, altering the STUN and rport should help.
STUN is located in "Configuration" -> "Accounts" -> your accounts -> "Network Settings".
If using Zoiper with Wi-Fi, 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 values are:
Server hostname/IP: stun.zoiper.com
Port: 3478 UDP/TCP
Refresh period: 30
