Portech MV-372

Portech MV-372 is a dual-channel VoIP GSM gateway that supports SIP, Caller ID, Caller ID, Speed Dial, SMS receiving and sending, call routing from the GSM network (MOBILE → LAN) and from the local network to the GSM network (LAN->MOBILE).

VoIP GSM gateway Portech MV-372 optimizes the work of the telephone network, saves time and money spent on telephone communication. Portech MV-372 provides communication between cellular networks of the GSM standard and IP networks without the use of any additional equipment.

Calls from mobile phones are addressed to the gateway, and then via the Internet (SIP operator) they are transmitted to landline or mobile phones. (In this case, long-distance communication rates and mobile operator rates are replaced by SIP operator rates (Internet telephony), which are several times cheaper). Even cheaper communication is obtained when transmitting a call from one gateway to another via the Internet (without using a SIP operator).
