<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>So I’ve added an additional PRI to our outbound route
group. This PRI does not have the feature where all outbound calls
are tagged as the main number. On the CUCM side this is not an issue as
all calls simply use the “External Phone Number Mask” field for the
line settings.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Our legacy PBXs also route through the CUCM to the gateways
for PSTN calls as well. They tend to ride the short bus. Meaning they
only send us the last 4 digits…which is great for on-net calls, not so
good for PSTN calls.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Our layout is:<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>[Legacy PBX] <-> [Voice GW1] <-> [CUCM (6.14)]
<-> [Voice GW2] <-> [PSTN]<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Is there a way I can get CUCM to tag on the area code/prefix
before it heads out to the PSTN without messing with calls from CUCM to PSTN?<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Just thinking aloud, I’d like to just add it at Voice
GW2 so we stay 4digit internally. However, I’m not sure how that
will mess with calls that CUCM is sending to PSTN, don’t wanna end up
with (123)456-(123)456-7890 for a (123)456-7890 call when I’m trying to
fix 3210 to look like (987)654-3210….if that makes sense.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I also need to look into the CER side of things (emergency
responder/E911) for how to identify these numbers for the PSAP. Which
will obviously change based on how the number looks when the call goes out.<o:p></o:p></span></font></p>
