ComXchange Tech Notes

ComXchange and its components are built around the Session Initiated Protocol (SIP). The SIP standard is an open specification known as RFC 3261, and is governed by the third-party Internet Engineering Task Force (IETF)—not by any equipment manufacturers. Because of its flexibility and ease of use, SIP is quickly becoming the communication protocol of choice. This means more and more SIP-based endpoints are arriving to the market every day. Ultimately this gives property owners and system administrators more choices as they look to find unique solutions to fit their various user's needs.

System Benefits

Centralized Administration

Administrators of multi-site systems—typically the servicing dealers—can use the graphical based administration tools to monitor and manage multiple sites from a single location.

System Logging

The system logs are stored in various SQL tables which allow administrators to selectively look at the data pertinent to them.

Modularity

Each component of the system is modular in nature. Analog station gateways (FXS), analog trunk gateways (FXO), and T1/PRI gateways are all self-contained units.

Controller Redundancy

The ComXchange controller is an industrial-grade server composed of a RAID 1 or RAID 5 disk array; hot-swappable hard drives; redundant, hot swappable power supplies; dual 100/1000 network interfaces; and dual-core processing.

System Redundancy

The ComXchange controller is designed with maximum uptime in mind, but it's important to note that the system can operate even without the ComXchange controller. The gateways and IP phones supported by the ComXchange system can identify when the controller is offline, and perform basic call routing without it.

Engineered Network

ComXchange comes with a network designed specifically to support voice quality. This is imperative to ensure toll-quality voice through the system 100% of the time. Key features include Type of Service (TOS) queues for Layer 2 switching, Quality of Services (QoS) queues for Layer 3 routing, and separate Virtual Local Area Networks (VLANs) for voice and data..
