<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Since SRST is required everywhere might as well have H323
gateways for each site. TEHO would normally require complex dial-plan on CallManager.
So I’m thinking H323 Gatekeeper would make this configuration much easier.
My questions center around the CallManager Dial Plan and its interaction with
Gatekeeper.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Here is what I am thinking for the CM Dial-Plan Deployment<o:p></o:p></p>
<ul style='margin-top:0in' type=disc>
<li class=MsoNormal style='mso-list:l3 level1 lfo2'>I will create a H323
Gatekeeper/Gateway network<o:p></o:p></li>
<li class=MsoNormal style='mso-list:l3 level1 lfo2'>CallManager Trunk/GK to
the GK network<o:p></o:p></li>
<li class=MsoNormal style='mso-list:l3 level1 lfo2'>Site specific 911 PT and route
patterns pointing to local GWs (RL, RG, H323-GW)<o:p></o:p></li>
<li class=MsoNormal style='mso-list:l3 level1 lfo2'>Site specific 7-digit
route patterns normalized to 10-digit (RL, RG, GK)<o:p></o:p></li>
<li class=MsoNormal style='mso-list:l3 level1 lfo2'>General 11-digit (Toll
Free and LD) (RL, RG, GK)<o:p></o:p></li>
</ul>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Questions<o:p></o:p></p>
<ul style='margin-top:0in' type=disc>
<li class=MsoNormal style='mso-list:l0 level1 lfo4'>Should I create a CallManager
GK/Trunk to the gatekeeper<o:p></o:p></li>
<li class=MsoNormal style='mso-list:l0 level1 lfo4'>Should CallManager Dial-Plan
point to GK/Trunk (RP, RL, RG-GK)<o:p></o:p></li>
<li class=MsoNormal style='mso-list:l0 level1 lfo4'>Should CallManager Dial-Plan
point to GK/Trunk the H323 Gateways for redundancy (RP, RL, RG-GK/RG-H323<o:p></o:p></li>
<li class=MsoNormal style='mso-list:l0 level1 lfo4'>Basically, could my CM
dial-plan consist of site-specific 911 patterns and Local and LD patterns
point to GK<o:p></o:p></li>
</ul>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I look forward to the discussion... <span style='font-family:
