Chapter 6 Setting up the private VoIP network 77SRG200/400 Release 1.5 Configuration Guideb Assign the Normal and SRG scheduled route for the two destination codes.Main office informationThe SRG requires information about the main office call server that is not needed for a BCM 4.0.Element Manager accommodates this information with SRG-specific panels that are activatedafter the SRG200/400 Release 1.5 keycode is applied. The information required for these panels isspecific to the main office call server “CS 1000 considerations” on page 33.External attendant supportThe SRG can use the BCM 4.0 Selective Line Redirection capability to provide an externalattendant. If the attendant is located in the main office, there are two ways to maintain theattendant if the VoIP trunks become unavailable:1 A fallback (or Prime) DN at the SRG can be specified. Since this DN is likely to receive callsin a WAN failure scenario, it must be an IP telephone that can transfer the calls to the desiredparty. If the IP set is also a redirected IP set, there is a period of time where inbound calls areun-routable, until the IP set falls back to the SRG.2 A fallback route to the main office call server over the PSTN can be configured. At the mainoffice, vacant number handling (such as routing to voice mail) can be applied.Note: The SRG does not have local attendant capability.
