1. GSM VoIP Gateway

The GSM VoIP Gateway (GoIP) provides the extension of GoIP and supports up to GSM channels. Each GSM channel can be programmed individually to establish the connectivity with IP-PBX, or can be bundled as a single trunk in connection with IP-PBX. It is ideal for VoIP to wireless services where a fixed telephone line (PSTN) is not available or for cellphone roaming via the a VoIP network. The GoIP4 brings mobility, scalability and significant savings on long distance charges.
