Interconnecting multiple Cisco BE3000 systems to accomplish a distributed UC solution


In some cases, when a remote office location is distant and does not have reliable data connectivity, it is better to install a separate BE3000 server at that branch office. In such cases, more than one BE3000 systems are required. Business owners need to connect these systems in such a way that employees in different locations are able to call each other without dialing via the PSTN, and using an abbreviated dial plan. This solution provides the following benefits:

• Each location with BE3000 still has telephony service even when connectivity with the main office

is lost.

• Employees can dial internal numbers to reach employees in another business location.

• Employees at each business location can dial PSTN calls via the local PSTN connection.

This solution provides only basic connectivity between the autonomous BE3000 systems. The limitations of multi-systems BE3000 solutions are as follows:

• Each BE3000 system has its own auto-attendant (AA) and voicemail (VM) system.

• Each BE3000 system has its own directory, and AA can perform dial-by-name only for local users.

• The site feature transparency does not work.

• PSTN calls must be routed from trunks registered on the local BE 3000.

• The busy lamp field (BLF) does not work across two BE3000 systems.

• Call park, call pickup, pickup groups, and hunt lists do not work across two BE3000 systems.

Note To achieve the same length dial plan across the combined solution, all BE3000 systems must have an extension rage with same length, such as 3-digits or 4-digits.
