Hi,
I download the zoiper premium package for IPHONE iOS, and notice the ZRTP encryption you are offering is only AES1 which is 128bytes, which is half of standard 256bytes used in AES3.
Why are you offering only low security features and NOT the AES3?
regards
I checked, the zrtp we wrote does the higher encryption too, but our srtp library does not implement the RFC for the 256bytes yet.
It is on the todo list, but i don't know when it will be done.
