Hello @Mekaeil Andisheh

Kindly note that the error you get indicates that for some reason, the provider's side cannot be reached.
As a first step what i would recommend is to check if you can resolve from the PBX's network to the FQDN of the provider using nslookup

Are you using your own DNS server or a public one?
