zoiper5 unable to connect to network on MacOS 10.14.6

Question

Trying to connect Zoiper5 running on MacOS 10.14.6 to my SIP account and Zoiper is unable to connect to network. 

I am running Wireshark and at no time is any SIP UDP / TCP traffic generated. Naturally, Zoiper fails to connect to SIP provider and just spins. 

For reference, Zoiper 3 running on older MacOS connects just fine to SIP provider. 

Is there some privacy/security selection I need to make for it on Mojave?

Thanks

Hi,

Probably you have not provided permissions in the Mac firewall for Zoiper5 to receive or make connections. 

You should check the system permissions first.

Thanks for your answer. 

That was the first thing I checked. Zoiper has "camera" and required and proper firewall access.

This is very odd then, no similar issue has been reported. However, Zoiper 5.4.5 has been released, which you can try.

See if it will make any difference.
