However, they cannot call any SRG analog (500/2500-type) telephones or
any external numbers through the SRG trunks because the Virtual Trunks are
not available. (SRG analog [500/2500-type] telephones are accessible if
alternate routing is available through the PSTN.)
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.
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 (500/2500-type)
telephones at the branch office. They can also be used to make outgoing
PSTN calls and receive incoming calls as usual. SRG IP Phones can access
the main office IP Phones or other branches by routing through the local
PSTN.
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.
