Right Fax may be your solution. you have to license how many concurrent calls the Right fax server can have. (I believe both inbound and outbound). so you could just dedicate 8 channels inbound then everything else will receive a busy....<div>

</div></div>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Hi everyone –</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I’ve been asked a question that I don’t know if I’ve heard before –</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I have two existing PRI circuits, built as a single trunk group, with about 1000 DID numbers on them, used for voice calls.</p>
<p class="MsoNormal">(for sake of mentioning it, the PRIs arrive on two different routers, and all the DIDs are reachable inbound on either one)</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Someone wants to add more DIDs for the purpose of faxing, with those DIDs being dedicated for fax usage, not for voice calls.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">But they want to limit the total number of calls that will be allowed to come in, so that we don’t ‘eat’ all 47 channels with attempted inbound faxes.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">How would I limit the allowable calls coming in to the DIDs 1500-1700 and 2100-2300 ?</p>
<p class="MsoNormal">(assuming 4-digit delivery from the telco)</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">One factor that might do it is that the session-target device mentioned below</p>
<p class="MsoNormal">only has two active channels – </p>
<p class="MsoNormal">Would that have the effect of stopping the 3<sup>rd</sup>, 4<sup>th</sup>, etc call and sending them back to the carrier</p>
<p class="MsoNormal">with a busy signal? </p>
<p class="MsoNormal">I don’t want a re-order tone – just busy.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Or would I use the ‘max-conn’ option as shown below under the dial-peer to ensure that</p>
<p class="MsoNormal">no more calls can come in?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I think my dial peers would look like this:</p>
