Recovery to Normal Mode
If an IP Phone is in Local Mode due to WAN failure or main office component failure, the SRG tries to communicate with the main office TPS at regular intervals. Once communication is established with the main office call server, the idle SRG IP Phones are automatically redirected and reregistered to the main office. IP Phones that were busy at the time communication was reestablished complete the call in Local Mode, and then reregister with the main office after the call is complete.
Local Mode operation
When an SRG IP Phone is in Local Mode, the user has full access to the services configured at the SRG (analog devices or analog or digital trunks) and to other IP Phones registered to the SRG. In Local Mode, the IP Phones can make local calls to other IP Phones and other analog
IMPORTANT!
When a telephone or trunk in the main office calls an SRG IP Phone that has switched to Local Mode due to WAN failure, the call is treated according to the main office call redirection configuration (such as forwarding to voicemail or continuous ringback).
Testing the telephone in Local Mode
From Normal Mode, the branch user has the option of going to Local Mode manually by resetting the telephone or using Test Local Mode. The test can be performed by the user at any time and does not require a password. This test is invoked from the IP Phone.
