VoIP GSM Gateways connect GSM or WCDMA or 4G LTE to VoIP networks to provide two-way communication: GSM/3G/4G to VoIP and VoIP to GSM/3G/4G. This allows you to connect most IP-based telephone systems including Yeastar IP Phone Systems, and softswitches to a GSM or 3G WCDMA or 4G LTE; which can provide a sophisticated fallback solution when landlines go down, or be used to increase call traffic capacity by providing additional dial-tone.BenefitsMobile networksLink up PBX systems with GSM or 3G WCDMA or 4G LTE networksSMSSend and receive SMS messages via Web interface and support bulk SMSEasy to installEverything can be easily set up in the Web based managementCost savingSave phone bills tremendously with mobile-to-mobile calls and SIP trunksBack upWork as a cost-effective backup when the landline network goes downEasy to integrateHigh compatibility with mainstream IP-PBX and softswitch6926150032842
