This issue is very similar to:
http://code.google.com/p/sipdroid/issues/detail?id=63
as I understand that ZRTP is the key exchange protocol and uses SRTP for the 
encryption. Adding SRTP without a key exchange protocol would not be very 
useful.

I'm very interested for TLS and SRTP support as I just upgraded my Asterisk 1.6 
to 1.8.3 and it supports both TLS for signaling (TLS encapsulated SIP via TCP 
port 5061) and SRTP.

Lumicall ( http://www.lumicall.org ) now has TLS support on Android.  It also 
adds support for DNS SRV, ENUM dialing and ICE/TURN for NAT traversal

The TLS support in Asterisk is not perfect, Kamailio might be a better option 
for server side TLS.
