Can ZRTP be used with H.323 or other signaling protocols?

Yes, ZRTP can be used with any signaling protocol, including SIP, H.323, MGCP, Jingle, and Peer-to-Peer SIP (which I think is a cool idea). The XMPP Standards Foundation has a protocol extension for “Use of ZRTP in Jingle RTP Sessions”, XEP-0262. ZRTP is independent of the signaling layer, because it does all its key negotiations in the media stream. In fact, Zfone now encrypts calls made with the Google Talk VoIP client, which uses Jingle for signaling instead of SIP (but only when Google Talk is using RTP for its media stream). ZRTP is the only VoIP encryption protocol with this much flexibility.
