Administering An Emergency Number - Avaya 9608 Administrator's Manual

Administering Telephone Options
If the VU_MODE value is 1 (Optional), the telephone presents the user with the Login
●
Screen with a Primary Phone yes/no toggle field, for the user to designate whether the
telephone is that user's primary phone. If the user selects "yes", then the phone operates
as a non-visiting user telephone and the inactivity timer is not applied. If the user selects
"no", then the telephone operates in the visiting user mode where an inactivity timer will log
the user off after a predetermined time.
If the value is 2 (Forced), the telephone is always in the visiting user mode and the
●
inactivity timer is always applied.

Administering an emergency number

Set the PHNEMERGNUM configuration parameter in the settings file to assign an emergency
telephone number. This telephone number will be automatically dialed whenever the Emerg
softkey is selected on the Login screen, or the Phone screen, or when the user chooses the Yes
softkey on an Emergency pop-up screen.
Note:
If SES/SM is not operable, Emergency Number calling is not operable. When
Note:
using UDP, the Emergency softkey may not work.
When in failover, the Emergency Number must be provisioned on the SIP
gateway or the user will not be able to dial it.
The local proxy routes emergency calls from a user at a visited phone so that the local
emergency number is called. When PHNEMERGNUM is administered, using the Emerg
softkey overrides the SPEAKERSTAT parameter setting or a user-selected referred audio path.
This means that the even if the Speakerphone is disabled it is the default transducer when the
user presses the Emerg softkey.
When the telephone is registered with an Avaya server and is in a logged out state, a call to the
Emergency number shows a SIP URI username of "anonymous" in the From and Contact
headers of the INVITE message. For example:
From: sip:anonymous@avaya.com;tag=-961235f46856f74-5_F135.8.62.174, and Contact:
<sip:anonymous@135.8.62.174;transport=tcp>) (Note that anonymous user support must be
configured on SM)
The telephone will always accept an incoming INVITE with a SIP URI username of
"anonymous" in the To header with the IP address of the telephone. For example:
To: <sip:anonymous@135.8.62.174;transport=tcp> (Note that anonymous user support must
be configured on SM)
This allows for incoming public service access point (PSAP) calls in both the registered inactive
state and the registered state.
