<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>However, when an inbound call is forwarded or transferred
from an IP phone to a user at a non-Cisco PBX site, we have voicemail problems.</span></font></p>

font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Let’s see if I can describe this clearly:</span></font></p>

font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>The destination voicemail systems tend to ‘see’
the Original Called Number that is being passed on the ISDN Setup messages, and
tries to find a match on the destination voicemail system for the number of the
IP phone, rather than that of the actual Called Number.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Example:</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Call comes inbound for IP phone 123.456.7890;</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Call is forwarded or transferred to external phone number
via PRI, 987.654.3210;</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>At destination site, the call comes into the PBX via PRI
with three phone numbers in the Setup message:</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>When the PBX passes the call to voicemail, the voicemail

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>So now to the question:</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>How can we SUPPRESS the Original Called Number on the outbound
leg of these calls?</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Do we set this on the gateway or on the cm phone parameters,
or elsewhere?</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Remember, the call translation in the normal sense is not
the issue: calls complete correctly, as far as their routing via the PSTN. We
just need to get rid of the pesky ‘Original Called Number’
information so it doesn’t get passed on to these destination voicemail
systems.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Any hints/suggestions would be appreciated</span></font></p>
