bAssign the Normal and SRG scheduled route for the two destination codes.

Main office information

The SRG requires information about the main office call server that is not needed for a BCM50. Element Manager accommodates this information with SRG-specific panels that are activated after the SRG50 keycode is applied. The information required for these panels is specific to the main office call server CS 1000 considerations on page 33.

External attendant support

The SRG can use the BCM50 Selective Line Redirection capability to provide an external attendant. If the attendant is located in the main office, there are two ways to maintain the attendant if the VoIP trunks become unavailable:

1A fallback (or Prime) DN at the SRG can be specified. Since this DN is likely to receive calls in a WAN failure scenario, it must be an IP telephone that can transfer the calls to the desired party. If the IP set is also a redirected IP set, there is a period of time where inbound calls are un-routable, until the IP set falls back to the SRG.

2A fallback route to the main office call server over the PSTN can be configured. At the main office, vacant number handling (such as routing to voice mail) can be applied.

Note: The SRG does not have local attendant capability.
