I'm looking for wireless telephones for my business that use a VERY secure encryption. The one that was quoted by our local telephone company uses DES encryption. Is this really that secure? If not does anyone know a company that does carry a more secure product at a decent price?
Our company does use a Nortel VoIP system and we are looking to expand with wireless sets that work with our BCM. Securely.

DES, Digital Encryption Standard, is no longer considered to be a secure form of encryption. It uses a 56 bit key size that is now considered too short. There were also concerns about a back-door in it. Triple DES was created and is considered secure. AES, or Advanced Encyrption Standard, is the latest encryption. See the link below for details.
We virtually take them for granted because they are very cheap to possess and maintain.
