<tt>In Enswitch, we have some places where we send out custom SIP
packets. These include:</tt>
<p><tt>* NOTIFYs for custom busy lamps, since handsets register to
an external registrar (Kamailio), we have multiple Asterisk
machines sending calls to handsets, and we support busy lamps
for things like parking slots.<br>
</tt></p>
<p><tt>* NOTIFYs for custom MWIs, since we have our own voicemail.</tt></p>
<p><tt><tt>* NOTIFYs asking handsets to reboot to pick up new
provisioning.</tt></tt></p>
<p><tt>* MESSAGEs for text messages to handsets.</tt></p>
<p>At present, we send these from our AGI daemon to the Kamailio
registrar using direct UDP. It would be nice to have Asterisk do
this for us in PJSIP, since Asterisk already knows how to
construct such packets and send them out.</p>
<p>Is adding a facility to send out a custom SIP packet something
that the Asterisk developers would be willing to add? If so, what
would it take to get this added?<br>
