Taiwan VOIP GSM Gataway is a Telecommunications product. Key specs — Origin: Taiwan.
Product Description
Specifications: Mv-370 VOIP GSM gateway is the comformity of mt-350 GSM interface and VOIP gateway.
One of application for mt-350 is to connect a VOIP gateway, and mv-370 takes the feature of mt-350 and VOIP gateway for call termination (voip to GSM ) and origination (gsm to voip), and efficient to utilize the same circuit of both, but without fxo and fxs interface transformation, this could save the material cost as well as improve the voice quality during communication.
Major function: 1. Voip(sip), GSM conversion. (mv-370) 2. Voip(sip), CDMA conversion. (mv-370c) 3.50 sets of LAN --> mobile routes setting,50 sets of mobile --> LAN routes setting. 4. Voice response for setting and status(dial in from mobile). 5. For call termination (voip to gsm) and origination (gsm to voip). 6.
Standard sip(rfc2543, rfc3261) protocol, communicates with other gateway or PC 7. All functions can be set on web. Specification: 1. Protocols: Sip (rfc2543, rfc3261) 2.
