Tell me what the SIP service provider will place calls to 8-800-100-77-33 and 8-800-200-00-00
Tried with MTT, SIPNET, COMTUBE - do not pass, the status is Busy or just drops
I understand that it is air - free, and that mobile phone call.
Need to be able to call it from the computer.
If possible have someone check the availability of dialing these numbers (if connected to a SIP provider)
