BLF List Subscription
When you configure the IP phone to monitor a list of specific remote lines, the IP 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 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">
