[cisco-voip] CallManager 4.1(3) and Encryption/Authentication forIP Phones

[Philip Walenta]

Well, there's also the gateways to consider, and if memory serves (I could
be wrong), if security is on, it's on for gateways globally.  There's always
mixed mode so secure and non-secure devices can both register, but I've not
played with it so I cannot vouch for how well it works :-)

They aren't and understand that CTI Apps do not support it.  However,
wouldn't you be able to configure the Agent phones as "non-secure" and be
able to use encryption but just not to agent phones?
