and telecommunications suppliers with new provisions for security, standards support, and interoperability.

Organizations can gain significant phone service savings, but "the return on investment for VoIP today is limited because of the lack of mobility in today's solutions," explains TeleSym CEO Bob Hart.
The latest generation of SymPhone is said to provide robust security features based on RSA Security's Keon digital certificate management solution that provides:
- Encrypted user authentication to standard directories (NT Domain, Active Directory and RADIUS) to initialize clients
- Application PKI (public/private key authentication) for all subsequent initializations of the client and its connections
- PKI authentication in inter-company communications.
TeleSym says its approach to call quality, called "Quality at the Edge", solves issues that cannot be addressed by network-based quality-of-service (QoS) approaches. By placing quality management in the client software, SymPhone:
- Maintains calls when the packet loss is as high as 50 percent
- Handles up to 400ms of jitter
- Manages up to 250msec of latency
- Manages across multiple networks and wireless access points, of mixed types
- Automatically reconnects calls that are temporarily interrupted.
The company says that SymPhone also applies least-cost routing algorithims which provides savings on both long distance toll charges and administration costs, by routing calls as far as possible over IP before connecting to the public telephone system.
TeleSym says it is a member of the Intel Communications Alliance and makes use of industry standards, including SIP (Session Initiation Protocol) and H.323 in conjunction with Intel NetStructure Host Media Processing (HMP) software for the server components of SymPhone. The company claims this makes its SymPhone System compatible with nearly all brands of VoIP and network equipment and software.
In addition, SymPhone connects to virtually any PBX or PSTN system or source, TeleSym adds. It is a "hardware-agnostic" system that can work with heterogeneous network environments, popular handheld devices and Windows-based PCs.
The pricing structure is simplified with this new release, to a per-user license fee for access to server software, subject to volume discounts. Multi-location installations may require supplementary server software, at additional cost. Additionally, the SymPhone Client Software is now available as a limited-time free
