Just downloaded Voiper 3 & registered "MyNetfone" on their system seems to dial ok but comes up with "SIP 408 - Request Timeout" also no incoming audio.

Using Windows 10 64 bit.

It works fine on my old laptop using Windows 7 & an older version of Zoiper.

Can anyone please help?

Please make sure you have the correct transport setting in Zoiper according to your provider's instructions. You might need to use UDP, TCP or TLS.

If using a SIP account, disabling STUN and / or Rport (or enabling it, depending on its current state) could help.

Please open settings -> Preferences;
click on Accounts;
select your account from the list on the left;
click on Advanced;
enable or disable STUN;
save the changes and try to recreate the issue.

Please also disable STUN globally for the application by following these steps:
- open settings -> preferences -> advanced -> network sub-tab -> STUN options

Please try to bypass STUN altogether, STUN is terrible technology.
