Why is Zoiper not working at home?

0 votes


I have downloaded Zoiper on my home laptop so that I can work from home but when I make calls there is no outbound sound. My headset is definitely set up properly and my internet is a good speed. I believe there is some kind of setting called STUN which could help? Could someone please tell me what this is and how do I apply it to Zoiper?

I use a link to the hosted dialler on google chrome (not sure if this is useful info or not)

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.

When registering an account on Zoiper I use the IAX option so does this mean it's not SIP? 

Also I noticed today that Zoiper actually works fine when I fully close Skype for Business - do you know if this has anything to do with it? I do actually need both applications running at the same time if at all possible


Start Zoiper, go to Settings -> Preferences -> Audio -> Device and disable USB HID devices support and yealink devices support.
After this, please try to make a call.
