www(dot)myKryptofon(com) has a full (not demo/beta) version of the app for free for a 14 day trial.
This app is completely set up for VOIP/SIP, but that's not the main purpose of the app. The app offers 256 bit encryption for your voice. Everyone knows BB does a good job of encrypting your data, but NOT your voice.
I would ask you to download the app and provide me with some feedback! I will be posting a full forum thread on this within the next 48 hours.
Here are some hard product specs...
Compatible on any global GSM carrier
Cellular GSM or WiFi capable
AES 256 bit encryption
NSA Suite B compatible authentication
Malware protection from rogue capture of the microphone
Encryption key rotation technology
Time activated encryption keys
Voice, chat and file transfer
Interoperability with our Windows Mobile and Windows product on GSM, CDMA, WiFi, Satellite BGAN, and Ethernet networks.
That looks like a neat product but what the market needs right now is a true SIP client, noty locked to any particular server and in my opinion with a one-time licensing charge in line with BlackBerry application prices and not a monthly fee.
I am not sure why you guys chose AES256 although it is relatively cycle-friendly, I would have expected a stream cipher would offer a lot better performance and acceptable security with key refreshing at appropriate intervals.
Thanks for you post! And you are 100% correct. The BB world needs a SIP client not locked to one service and a one time fee. Thanks to you and many other providing feedback on these boards, we will have this app available hopefully within 30 days. As I have asked on other threads, what would you pay for an app like this?
We know the current product is not for the average user, however, it has given us the chance to put it out there, and listen to the demand for a SIP client.
