Hi All,

              If a SIP device sends subscribe request for a address of
record to a SIP server than SIP server generally sends PIDF  XML in NOTIFY
message something like given below which is published by the AOR user:

<?xml version="1.0" encoding="UTF-8"?>
<presence xmlns="urn:ietf:params:xml:ns:pidf"
    entity="pres:abc at google.com">


        <rp:unknown />

If no PIDF document is published for the AOR then in that case what XML SIP
server should send to presence subscriber in NOTIFY request body ?

Regards ,
