Analog-to-SIP Gateways to Meet All Your Business Needs

The MG line of analog-to-SIP VoIP gateways enhances Zultys IP phone system coverage of legacy analog devices. MG Gateway makes it easy to integrate legacy phones, fax machines, and credit card readers into the company’s communication solution. An MG Gateway converts the phone call format to pass between the SIP network and the public switched telephone network. Bring analog phones fully into the Unified Communications environment. Enable Presence, Status, and other service features in the Zultys ZAC Unified Communications client for analog users. Make it easier to contact others in the company regardless of the device they use for phone calls. Zultys enables our customers who deploy our virtual or hosted solution to support PSTN calls via FXO MG gateways. Take advantage of the flexibility of a virtualized phone system, even if you need to keep a PSTN line active for your business.
