Zoiper does not always register when WiFi becomes available

Question

Using Zoiper for Android on my Galaxy S6. 

Configured it so that it only uses WiFi networks. 

Sometimes when my phone connects to WiFi Zoiper registers automatically: wonderful! 

But sometimes it doesn't. Then I have to start Zoiper manually. 

What's going wrong? 

Answer 1

If your account cannot register for some reason, Zoiper will display an error message below the account name in the Accounts section. Please check for that error message.

Please try to alter "STUN" and rport for your account and try to register again. Both options are located in "Configuration"->"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 values are:
Server hostname/IP: stun.zoiper.com
Port: 3478 UDP/TCP
Refresh period: 30

Thanks, I'll keep that in mind. For now I switched to Zadarma, which seems to work for my use case out of the box and makes the "only WiFi" setting easier to find.
