Does voipo support protecting VOIP connections from interception by anyone with access to the data (like anyone else who is on a shared wifi connection)? Open source packages for intercepting VOIP conversations include http://www.voipmonitor.org/product-a...nitor-software and http://oreka.sourceforge.net/

In particular, does voipo support any VOIP encryption standards like SIPS, SRTP or ZRTP?
