<tt>Hi Pasan,<br>
<br>
It is about filtering based on SIP methods. During registration,
an UAC may list the supported SIP methods for that registration
(like INVITE, MESSAGE). If the filtering is activated during the
lookup() for a SUBSCRIBE, the lookup will fail as the current
methods does not match the supported methods in the registered
contact.<br>
<br>
Regards,<br>
