I'm able to make calls with the same SIP account using apps like Telephone and also from my Android using CSIPMobile, but not with ZoiperH5. I always get a message "This call is not covered by your tariff plan" when I try to make a call.
Zoiper is registered with the SIP provider as I can see the green check mark.
What could be the reason?
