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.
