I'd like to see the OBi devices support making secure calls with ZRTP, SIP TLS and SRTP. I have played with zfone and the secure builds of CSipSimple and I think this could be a valuable addition to the OBis.

There is a new beta release available called 1.3
- Support for SIP over TCP/TLS.
- SRTP (S-Descriptor Authentication)
You might be closer than you think to having some of those features.
Is this feature already implemented? It is the one thing holding me back from buying on OBi.
