V7111 Analog Media Gateway (FXO), 4 Channels MAINTAIN UNIVERSAL CONNECTIVITY
With 3Com VoIP gateways, organizations can retain PBXs and analog devices for operational or budgetary reasons while they implement IP telephony in a phased overlay. Employees can continue to use familiar equipment and interfaces, including dialing plans, email systems, fax
machines and modems. The SIP-compliant gateways may be positioned between the IP network and any brand of PBX to deliver calls or appli- cations such as the SIP-based conferencing and call center capabilities of the 3Com Convergence Applications Suite.

IMPLEMENT REMOTE SITE SURVIVABILITY
In environments where remote branch sites are dependent on a single wide-area IP network connection to the 3Com IP Telephony Module, a local analog gateway enables incoming and outgoing calls to the PSTN. This capability provides telephony survivability and business continuity
for the remote site even if its IP connection has been compromised.

REDUCE TELEPHONY COSTS
As part of a converged communications solution, the gateways let enterprises reduce PSTN costs by implementing least-cost routing featuresdelivered by the 3Com IP telephony platform. To minimize long distance calling charges, calls can be routed to the most cost-effective gate-way. Plus, remote sites can retain PSTN connections for supporting local Direct Inward Dialing (DID or DDI) numbers, and for receiving the lowest local call tariffs from their communications service provider.
