Details of Configuration Parameters:
dialplan.emergency.asserted_id_source
Description:
Configures the precedence of source of emergency outbound identities when placing an
emergency call.
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.
If it is set to CUSTOM, the custom outbound identity configured by
“dialplan.emergency.custom_asserted_id” will be used; if the value of the parameter
“dialplan.emergency.custom_asserted_id” is left blank, the LLDP-MED ELIN value will be
used.
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.
