Blf/Blf List Subscription Configuration - Yealink SIP-T3 Administrator's Manual

Administrator's Guide for SIP-T2 /T3 /T4 /T5 /CP920 IP Phones
When you configure the IP phone to monitor a specific line, the phone sends a SUBSCRIBE request with Request-
URI containing the monitor line URI to the server, and then receives a NOTIFY request. The NOTIFY message con-
tains an XML body with the status of the specific monitored line.
The following example shows a NOTIFY message for a BLF line "012":
<?xml version="1.0"?>
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="1" state="full" entity-
y="sip:012@10.20.10.42:5060">
<dialog id="0000" > <state > terminated</state > </dialog >
</dialog-info>
BLF List Subscription
When you configure the IP phone to monitor a list of specific remote lines, the phone sends a SUBSCRIBE request
with Request-URI containing the BLF List URI, and then receives a NOTIFY request. The NOTIFY message con-
tains an XML body with the status of each monitor line.
The following example shows a NOTIFY message for a BLF List, the BLF List contains 4605 and 4607:
<?xml version="1.0" <?xml version="1.0"?>
<list xmlns="urn:ietf:params:xml:ns:rlmi" xmlns="urn:ietf:params:xml:ns:rlmi" version="0" fullState="true">
<resource uri="sip:4605@pbx.yealink.com">
<name > 4605 Yealink</name>
<instance id="JQZxud2qeo" state="active" cid="8y35ri@broadworks"/>
</resource>
<resource uri="sip:4605@pbx.yealink.com">
<name > 4607 Yealink</name>
<instance id="pXHQ97tPyQ" state="active" cid="tYzwJM@broadworks"/>
