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.
Small enterprises should really enjoy the Grandstream GXP280 and GXP285 devices, due to mixture of high quality of sound, graphic LCD display and rich list of business features.
