dialplan.emergency.X.server_priority
(X ranges from 1 to 255)
a combination of
digits 1, 2 and 3
1, 2, 3
Description:
Configures the priority for the emergency servers to be used.
The digits are separated by commas. The servers to be used in the order listed (left to right).
The IP phone tries to send the INVITE request to the emergency server with higher priority. If
the emergency server with higher priority does not respond correctly to the INVITE, then the
phone tries to make the call using the emergency server with lower priority, and so forth.
The IP phone tries to send the INVITE request to each emergency server for three times.
Example
:
dialplan.emergency.1.server_priority = 2, 1, 3
It means the IP phone sends the INVITE request to the emergency server 2 first. If the
emergency server 2 does not respond correctly to the INVITE, then tries to make the call
using the emergency server 1. If the emergency server 1 does not respond correctly to the
INVITE, then tries to make the call using the emergency server 3. The IP phone tries to send
the INVITE request to each emergency server for three times.
Note
: If the IP address of the emergency server with higher priority has not been configured,
the emergency server with lower priority will be used. If the account is registered
successfully or failed (the account information has been configured), the emergency calls will
be dialed using the following priority: SIP server>emergency server; if the account is not
registered, the emergency server will be used.

Hotline
Hotline, sometimes referred to as hot dialing, is a point-to-point communication link in which a
call is automatically directed to the preset hotline number. The IP phone automatically dials out
the hotline number using the first available line after a specified time interval when you lift the
handset, press the Speakerphone key or tap the line key. IP phones only support one hotline
number.
