The Simton IPX is a hybrid IP PBX with optional, but very rich features found in full PBXs, VoIP gateways, IP routers, and firewalls. The Simton IPX has flexible and reliable methods to connect with PSTN's, the Internet, and VoIP networks.
Using Simton's distributed VoIP technologies, an enterprise customer with branch offices can easily build a data and voice VPN (V²PN). The Simton IPX can convert a legacy PBX into an IP PBX and migrate existing voice and data networks into a convergent network.
For VoIP service providers, the Simton IPX is an ideal CPE for individuals, SOHO and enterprise customers. The Simton IPX is easy to manage and very cost effective.

PBX Features:
The Simton IPX supports analog phones and analog/digital trunks to the PSTN (central office). It has built-in PBX features including auto attendant, caller id, 3-way calls, call transfer and many other useful features. The Simton IPX also provides life line support that allows some phones to connect to the PSTN during a power outage.

VoIP Gateway:
The Simton IPX supports standard VoIP protocols. Multiple VoIP accounts can be shared by the local extensions on one Simton IPX. With VoIP services from an ISP, communications costs, especially for long distance calls, can be significantly lowered. Many PBX features such as DID and ACD are also available for the VoIP connections.

Voice Intranet:
Multiple Simton IPX systems can form a mesh voice intranet or a star voice intranet (also called Voice VPN in general). An organization using Simton's distributed VoIP technologies does not need a centralized soft switch. 2 or 3 Simton IPX's can form the simplest voice VPN, which can grow to any size if needed. A Simton IPX based voice intranet can be viewed as a virtual wide area PBX over an IP network. Call transfer, conference calls, unified dialing plan, mobile office, contact center and many applications are available and/or can be easily configured.
Using the PSTN interfaces of Simton IPX and IPX based voice intranet, especially when global locations are involved, can intelligently route voice calls to destination PSTN numbers with the lowest cost.

IP Routing and NAT:
On the WAN side, the Simton IPX supports PPPoE, DHCP, and static IP routing for selective ways to access the Internet. The Simton IPX has NAT capabilities and provides DHCP and DNS services to PC's and other IP stations in a private LAN.
