Summary:                    Adding ZRTP security protocol support for asterisk
Description: 
Support is to be added for handling ZRTP protocol ( www.zfoneproject.com)
in Asterisk. ZRTP is the security protocol that secures the RTP stream.
Philip Zimmermann is the primary designer of the protocol and has developed
the libzrtp library implementing the protocol.

The ZRTP-support will handle the following scenarios

1.There is a need to Monitor traffic, handle DTMF between a caller
(Authenticated user of PBX) & a callee (Authenticated user of PBX).

2.There is a need to Monitor traffic, handle DTMF between a caller
(Authenticated user of PBX) & a callee ( not an Authenticated user but on
RTP ).

3. There is a need to Monitor traffic, handle DTMF between a caller
(Authenticated user on PBX A) & a callee ( a Authenticated user on PBX B).

4.There is a need to Monitor traffic, handle DTMF between a caller
(Authenticated user of PBX) & a callee ( not a Authenticated user and not
on RTP ).

5.There is a need to Monitor traffic, handle DTMF between a caller
(Authenticated user of PBX) & a callee (a Authenticated user and not on RTP
).

6. When both peers have no Media Translation, DTMF handling needs
