Debug port security
The Debug port option can be manually changed on a per-phone basis. The change survives an IP
Deskphone reboot.
The Debug port option cannot be changed while the vxshell is active on the IP Deskphone (that is,
vxshell is accessed through the PDT). If an attempt is made to change the option while the vxshell is
active, the error message Cannot change Debug port is displayed on the phone screen. There
is no way to change the Debug port option through provisioning or configuration files
When the Debug port option is disabled, and a dongle is connected to the IP Deskphone, the
dongle is disabled from the initial startup of the IP Deskphone and neither input nor output debug
information is available. When the Debug port option is enabled, the debug port of the IP
Deskphone can be used for connecting a debug dongle.
If an Expansion Module is connected to the AEM port, it is recognized and is fully functional
(EXP_MODULE_ENABLE parameter must be set to YES), regardless of the Debug port option
setting.
In SIP 4.4 and later, the "magic key" sequence to switch between dongle mode and Expansion
Module mode ([MUTE]-[UP]-[DOWN]-[UP]-[DOWN]-[UP]-[2] for dongle mode and [MUTE]-[UP]-
[DOWN]-[UP]-[DOWN]-[UP]-[1] for Expansion Module mode) is not supported.
