911 Emergency Services Support
For IP telephones in local mode, and for other telephones at the SRG, the Networking
Configuration Guide (NN40020-603) provides details for configuration of 911 emergency
services.
For redirected IP telephones in normal mode, the IP telephone is registered with the main office
call server. Ensure that the main office call server is configured so that a 911 call from an IP
telephone at the SRG is routed back to the SRG’s local PSTN.
