Registering the IP telephones at the SRG50: Test Local Mode
When the IP telephones are configured (refer to “Setting up IP telephones” on page 63 ), they
automatically register with the CICM (S1). To register the IP telephones at the SRG50 (S2), use
the Test Local Mode option to redirect the phone to the SRG50. The Test Local Mode option is
available under the Diagnostics menu of the supported IP telephones.
The first time that the telephone is redirected to the SRG50, the telephone remains connected to
the SRG50 until it is configured at the SRG50 as a redirected set and the
Redirect Set button is
pressed (refer to “Configuring IP telephones for redirection” on page 55 for details).
On subsequent occasions, you can exit Test Local Mode by waiting for the feature to time out or
by pressing the key with the Exit button (
). This button is active only when the telephone
is in the local mode test. If the phone does not have an Exit button, you must wait until the test
times out.
Firmware upgrade
The redirected IP telephones at the SRG50 are under the control of the main office call server for
the majority of their deployment and receive all of their features in that context. Therefore, the
version of IP set firmware is aligned with the requirements of the CS 2000.
Note: The Diagnostics menu option is available on the supported IP
telephones only if the Disable Diagnostics Menu parameter on the User
Profile and Profile overrides pages of the CICM Element Manager is set
to No. If the Disable Diagnostics Menu parameter is set to Yes, the
Diagnostics menu option is not present on the user’s main menu. To
view or to change the Disable Diagnostics Menu parameter, refer to the
CICM Configuration Management document, NN10240-511.
Note: If an IP telephone is redirected to the SRG50 because the
connection to the main office has become unavailable, the SRG50 does
not attempt to redirect the phone back to the main office until Test Local
Mode times out. This is true even if connectivity to the main office is
reestablished before the test times out. Redirection to the main office can
be invoked manually by pressing the Exit button.
