[Freeswitch-users] any VOIP service provider support the freeswitch now?

I like to try out the freeswitch in real life call, but besides the connection through the asterisk, it seems that it has no way to directly support by VOIP service provider. I am sure some of the VOIP service provider do see the potential business in this area, but not sure why we still didn't see the crowded. Can someone share with me the list of the VOIP service provider who can support the freeswitch connection, or any good method to connect to VOIP service throguh the SIP. Thanks. David
