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.
By using Portech SBK-32 expander for 32 SIM-cards, you can increase the number of channels in the Portech MV-37X GSM VoIP gateway series using the Internet.
