[Freeswitch-users] Favorite SIP Providers? Australian providers?

I was looking through the list of Providers with example configs in the wiki: http://wiki.freeswitch.org/wiki/SIP_Provider_Examples I was wondering if anyone had a provider that they really loved? And why? I've got inbound 1800/0800 in UK & USA already, but might change. Also interested in outbound. Also, I want to get a 1800 number in Australia - any suggestions? Sorry in advance if this is one of those questions that does the rounds a couple of times a year (I did have a look through the archives via Google and didn't see anything), or if I'm treading on dangerous ground asking for recommendations of commercial services - so I guess only recommend services you use, not services you provide ;-) Cheers, Fraser
