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

By: Jason Parker (jparker) 2007-07-30 17:36:22 My question from 3 weeks ago wasn't answered, and there has been no patch uploaded, so I'm going to assume that this is a feature request. Closing.  If you do have a patch for this, please feel free to reopen. If it's a feature request, I would recommend putting up a bounty for it. By: Sagar Pai (sagarpai) 2007-07-30 21:11:26 This is work in progress, I am in the process of adding a patch to handle the ZRTP protcol in Asterisk. By: Russell Bryant (russell) 2007-11-06 22:48:46.000-0600 I am really excited about having support for zrtp in Asterisk.  :) However, I'm going to mark this issue as suspended for now.  We just try to keep reports closed that we're not currently working. If you'd like to discuss any implementation details, then I know myself and others would be happy to talk about it on the asterisk-dev mailing list.  Then, head on back over here if you would like to post some patches for others to take a look at. Thanks!
