<p class="MsoNormal" style="background:white"><span style="font-size:12.0pt;font-family:"Arial","sans-serif";color:#222222">According to RCS 5.1 spec clients can send PUBLISH SIP messages

<p class="MsoNormal" style="background:white"><span style="font-size:12.0pt;font-family:"Arial","sans-serif";color:#222222">When i searched the permanent presence state RFC its main aim
seems to set presence information once a user does not have o active

presence state directed me to think that this is a one of the options that
client may choose.</span><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:#222222"></span></p>
