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
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
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.
