<b>Subject:</b> [cisco-voip] Dry Closure Phones</span></p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">An app we are installing at our Police Dept requires the phones to have a "dry closure" contact or something like that.<br>
If I google this, I see a Dry Closure thing for 2600/3600 series, so I am researching that.<br>
Do any phones supported by CCM 8 support dry closure? Ultimately, I want the phones to work with SRST, so I probably don't want to stray too far from the Cisco wagon...<br>
<br>
Appreciate any insight.</p>
