I have VoIP service from my Internet provider. They do not provide Softphone. So I use their ATA adapter with analog phone.
On ZoiPer website I found info that for making call we need:
ZoiPer software installed, VoIP connection and credentials from provider.
I set up account entering my VoIP account name and password for my ADSL connection (using Windows 10 as OS).
user name in form firstname.lastname@example.org
When connect I get SIP 923 - No DNS results.
when nslookup, only primus.ca could be resolved but not xxxx.primus.ca
Should I ask them for IP for xxxx.primus.ca?
... is it possible at all to use soft phone in scenario I am trying to do.
I want to call from my pc through my VoIP/Internet provider. Or I have to be registered with some third party PBX?
