<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif"'>One
site which has only a 128k link into it has 3 ISDN lines (6 channels).
All inbound calls hit an Unity Auto Attendant through the WAN so with 6 ISDN
channels there’s potential of easily over subscribing the 128K WAN.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif"'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif"'>On
testing this, I’ve come to realise that the CAC/AAR is not functioning
correctly, but only where the CTI route point in concerned. When the
calls come in, they’re directed to a CTI Route Point which puts the call
into Unity. I have the CTI RP set up the same way as any extension on
that site. As a test, if I lower the bandwidth allocation of the remote
site to something that wont’ even allow one call and I attempt to call another
phone across the WAN, CAC/AAR kicks in and the call is rerouted out through the
PSTN. However if I try to call the CTI Route point extn#, the CAC kicks in but
it doesn’t reroute the call, so the call is prevented from connecting across
the WAN but not rerouted out to the PSTN.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif"'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif"'>When
I call into the site externally, where the incoming call is translated to the
CTI Route Point, the caller hears ringback. This doesn’t make sense
as if the call got through the route point, the AutoAttendant would answer.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif"'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif"'>So
basically, AAR isn’t working for my CTI Route Point, and callers are
hearing ringback even though CAC has prevented the call from connecting to the
route point.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif"'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif"'>I
have read something about route point and AAR and I will keep digging but I don’t
even know what to look for regarding the ringback when nothing is actually
ringing.<o:p></o:p></span></p>
