[cisco-voip] Dry Closure Phones

[Lelio Fulgenzi]

Yes, it looks like it has the more common telco style stipped end and screw type connectors. That's cool.

Great! I didn’t know they came out with a new one! The original had 66 style punchdowns for the wires. This one looks to use more convenient methods. Looks like you still have to make your own power wire though J

...and it looks like the TAM-B has been updated to the TAMB2!

With contact closure, you use a pair of wires to create a loop to signal a channel open, and a separate pair of wires to carry the audio (traditional tip and ring pair). You cannot do this without an adaptor. The best way I have found is to use a bogen tam-b or a pagepal, connected to an FXO port.

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.
