By mobile phone via SMS Callback
How it works?
The service is based on callback technology(Callback).
The essence of technology is: to connect you and the one you are calling, it creates a compound that is called "two-arm", while SIPNET server initiates two successive calls (or more in the case of a conference call), and then combines them into a single dialog.
For the SMS Callback, send an SMS message to +79994446543 indicating the phone number you wish to call.
For the conference callback send a SMS to the number +79994446543 and in SMS enter the word "multi" and a few numbers of participants.
