Example service (continued)

3. INVITE sip:[slp:/d=alarmclock, r=bedroom, u=maguire]@home.net SIP/2.0
   From: sip:announcement@alarmclock.net
   To: [slp:/d=alarmclock, r=bedroom, u=maguire]@us.chips.home.net
   Via: alarmclock.net
   Content-type: application/sdp
   [SDP for uni-directional RTP stream]

   Now the SIP Proxy at home.net looks up

   [slp:/d=alarmclock, r=bedroom, u=maguire]@home.net and determines that it is
   [slp:/d=alarmclock, r=guest_bedroom, u=maguire]@ua.marks.home.net]
   so it forwards the messages to the SIP proxy at marks.home.net

4. INVITE sip:[slp:/d=alarmclock, r=guest_bedroom, u=maguire]@ua.marks.home.net] SIP/2.0
   From: sip:announcement@alarmclock.net
   To: [slp:/d=alarmclock, r=bedroom, u=maguire]@ua.chips.home.net Via: home.net
   Via: alarmclock.net
   Content-type: application/sdp
   [SDP for uni-directional RTP stream]
