Category: 4G LTE Cellular, VoIP Gateways

VoIP to GSM and 4G cellular gateways let you extend your existing communication infrastructure while cutting call costs. They bridge IP-based systems with mobile networks, delivering flexibility without major upgrades. These gateways allow IP Phone Systems, standalone IP phones, IP alarm systems, and IP intercom stations to place and receive calls over 4G / cellular networks. As a result, businesses gain reliable mobile connectivity alongside their VoIP environment.
