Mitel 6800 Series SIP Phone Release 4.2.0 Administrator Guide
• Allows you to configure time interval between successive LLDP Data Unit (LLDPDU)
frames.
• Allows LLDP packets to be received from the LAN port.
• Allows the phone to use the location information, Explicit Congestion Notification (ECN)
Emergency Location Identification Number (ELIN), sent by the switch, as a caller ID for
making emergency calls.
• When LLDP ELIN is enabled (default), if the phone receives location information in
ECN ELIN format (10 to 25 numeric string), the phone replaces the caller ID in the
From header with the ECN ELIN value and the SIP URI does not change. The phone
determines if this is an emergency number by checking the emergency dial plan con-
figured on the phone. For example, the From header of a call from 405 at the IP address
192.168.0.20 on port 5060 with an ELIN of 1234567890 would contain:
From: "1234567890" <sip:405@192.168.0.20:5060>;tag=929293baab
• You can configure the phones to add an "elin=number" value to the From header
indicating the call is an emergency call, by defining the "use lldp elin" parameter as
"2". With the "use lldp elin" defined as "2", using the example above, the From header
would contain:
From: "1234567890"
<sip:405@192.168.0.20:5060;elin=1234567890>;tag=929293baab
Mitel IP Phones have a 32 second time-out for listening to LLDP-MED responses when the
phone is booting up. If LLDP-MED responses are received after this initial listening period, the
phone will ignore the response. Administrators can configure this time-out interval using the
"lldp startinterval" parameter. This parameter is only valid during the phone bootup process
and it will control the LLDP-MED time-out interval where the phone sends LLDP-MED
advertisements and listens for the LLDP-MED responses from the switch before proceeding to
the DHCP stage. The default value of this parameter is 32 seconds.
Administrators can also now configure the optional Link Layer Discovery Protocol for Media
Endpoint Devices (LLDP-MED) Inventory Management type-length-value (TLV) sets. Using the
"lldp optional inventory management tlv" parameter, Administrators can configure the phone
to either send all Inventory Management TLV (1) sets or to send none (0). The default for this
parameter is (1).
The following table identifies the configuration parameters for LLDP and ELIN and which method
you can use to configure each parameter. This table also indicates whether the parameters
can be configured by an Administrator, a User, or both.
