GSM VoIP Solutions
Configurations of GSM/VoIP networks allow the service providers to avoid the local Wired Public Switched Network (PSTN) in communication with a GMS mobile handset. As a result, the high rates charged by telephone companies are avoided.
For one time advertising promotions or typical requests it is easier to use services of the outsourced call center. Main advantage of such a service is that the company who rents it is free from the necessity of keeping the operators and organizing their work flow.
