Support Vivox's Bobsled VoIP telephony client

Vivox开发者_运维百科 launched the Bobsled application for the Facebook comunity. But is there a geteway available for the public VoIP network ?

I would like to initiate a Jingle/RTP and/or SIP/RTP call from/to the public VoIP network.

It would be nice like the XMPP Gateway to use my native VoIP desk-phone or soft-phone talking with my Facebook frinds.

According to the PRs, T-Mobile & Vivox plan to introduce connectivity to the public network.
