SIP (Session Initiation Protocol) is the underlying power of the Zultys MX IP PBX platform. SIP is an Internet Engineering Task Force (IETF) standard protocol for initiating an interactive user session that involves multimedia elements such as video, voice, and chat.
Zultys’ MX250 and MX30 are built on an open standards IP PBX platform based upon the SIP standard. Zultys systems provide a powerful platform to deploy, manage and use SIP based IP phones and other third party SIP devices. By supporting IP open standards, Zultys ensures that not only do Zultys IP Phones operate with the MX system, but a host of other devices, such as third party SIP-based IP phones, conference room accessories, paging equipment, application servers, video phones and video conference servers are supported, as well.
Zultys’ MX25 is a SIP gateway built on the same platform as the MX250. In addition to its gateway functions the MX25 can be used to expand the number of available PSTN module slots available in an MX250 or MX30. The MX25 may also be deployed as a stand-alone SIP gateway to IP-enable non-SIP compliant legacy telephone systems.
