Correct me if I am wrong, Dry Closure or Contact is not for the phones itself, but that allow you to run bells or chimes, or door openers. I have read about Valcom units doing this for stuff like Door openers. I am looking into it but try out ( http://www.valcom.com/techsupport/ip_solutions/ip_intercomdoorphones.htm ). Stab at the correct web page, but it is at this web site or call them and ask.

>From what I understand, dry closure or contact has to do with the isolating of any electrical equipment from the atmosphere. For example, if you were working in an area with volatile gases, you'd want a dry contact telephone. I think this is only available in analog sets for now, so you might have to deal with a VG22x gateway that registers to SRST and feeds the analog dry contact phone.

An app we are installing at our Police Dept requires the phones to have a "dry closure" contact or something like that. 
If I google this, I see a Dry Closure thing for 2600/3600 series, so I am researching that. 
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... 

Appreciate any insight.
