I have implemented voice encryption on my Cisco ip phones.
However,i captured the network traffic during a conversation and i don't see rtp (or SRTP)p packets in my capture.
Only a lot of UDP packets and this only during the converstation,so when people actually are speaking.
Anyone who has an idea? Is this correct behaviour?
I should be able to find an SRTP stream or something so i can rebuild the voice stream?
I want to test if the encryption is ok,so i need to hear anything except voice :)
Thanks for some feedback.
