Legacy Integration
ShoreTel 6.1 provides a migration solution from a legacy TDM-based voice network
into the voice-over-IP ShoreTel 6.1 system. You can handle line growth and enable a
migration of users from the legacy system to the ShoreTel 6.1 IP PBX by deploying the
ShoreTel 6.1 system at one location in a multi-location enterprise, or side-by-side with
a legacy PBX at a single location.
Integrating the ShoreTel 6.1 system with your legacy PBX's allows users on the different
systems to communicate with each other effectively for both phone calls and using
voice mail.
With an integrated voice network:
• Simplify communications for your users with an enterprise-wide coordinated
dialing plan using extension dialing.
• Exchange voice mail messages between users on different sites using different
voice mail systems. Standard commands such as compose, forward, and replay
extend the value of your different voice mail systems.
• Consolidate trunks with different traffic types to leverage different service
provider rates.
• Reduce service costs by redirecting inter-site calls across your IP network.
