If you do not enable signaling encryption, you increase the risk of exposing sensitive information (such as credit card or other identification numbers) to the public in TCP/IP communications. For example, if you do not use signaling encryption, and your DMCC applications rely on button presses (to convey a credit card number, for example), these button presses are exposed, because DTMF digits are passed in the signaling channel.

AE Services strongly recommends that you enable signaling encryption, which is described in the next topic, Administering security profiles for signaling encryption. |
