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 contains 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"/>
</resource>
</list>
