emergency routing, avoiding that emergency calls could not get through because of the server failure. If the phone is
not locked, it checks against the regular dial plan. If the phone is locked, it checks against the emergency dial plan.

Emergency Dialplan Configuration
Emergency Dialplan Configuration
The following table lists the parameters you can use to configure emergency dialplan.
Parameter dialplan.emergency.asserted_id_source <y0000000000xx>.cfg
Description
It configures the precedence of the source of emergency outbound identities when placing an emer-
gency call.
Note: If the obtained LLDP-MED ELIN value is blank and no custom outbound identity, the PAI header
will not be included in the SIP INVITE request. It works only if “dialplan.emergency.enable” is set to 1
(Enabled).
Permitted
Values
ELIN-If it is set to ELIN, the outbound identity used in the P-Asserted-Identity (PAI) header of the SIP
INVITE request is taken from the network using an LLDP-MED Emergency Location Identifier Number
(ELIN). The custom outbound identity configured by “dialplan.emergency.custom_asserted_id” will be
used if the phone fails to get the LLDP-MED ELIN value.
CUSTOM-If it is set to CUSTOM, the custom outbound identity configured by “dial-
plan.emergency.custom_asserted_id” will be used; if “dialplan.emergency.custom_asserted_id” is left
blank, the LLDP-MED ELIN value will be used.
Default ELIN
Parameter dialplan.emergency.custom_asserted_id <y0000000000xx>.cfg
Description
It configures the custom outbound identity when placing an emergency call.
Note: It works only if “dialplan.emergency.enable” is set to 1 (Enabled).
Permitted
Values
10-25 digits - for example, 1234567890. The SIP URI constructed from the number and SIP server (for
example, abc.com) is included in the P-Asserted-Identity (PAI) header (for example, <sip:1234567890@-
abc.com>).
SIP URI - for example, sip:1234567890123@abc.com. The full URI is included in the P-Asserted-Identity
(PAI) header and the address will be replaced by the emergency server (for example,
<sip:1234567890123@emergency.com>).
TEL URI - for example, tel:+16045558000. The full URI is included in the P-Asserted-Identity (PAI) header
(for example, <tel:+16045558000>).
Default Blank
Parameter
dialplan.emergency.server.X.address
[1]
<y0000000000xx>.cfg
Description
It configures the IP address or domain name of the emergency server X to be used for routing calls.
Note: If the account information has been configured (no matter whether the account registration suc-
ceeds or fails), the emergency calls will be dialed using the following priority: SIP server>emergency
server; if not, the emergency server will be used. It works only if “dialplan.emergency.enable” is set to 1
(Enabled).
