[Freeswitch-users] Scalable voip providers

[Daniel Swarbrick]

I'm working on a project that requires pstn "break-in" (ie, forwarding
pstn numbers to a sip trunk) in the UK, to a Freeswitch box that will
also use a (possibly different) sip trunk provider to dial numbers in
the US.

In the UK, we will eventually need contiguous blocks of perhaps a few
hundred numbers (although most numbers will just step to an available
channel), and may handle up to a few hundred simultaneous calls.
Likewise, the sip trunk provider for outbound dialling needs to support
potentially up to a few hundred calls, although these call volumes won't
be there initially - more like probably about 20-30 simultaneous calls.

I've done a fair bit of searching, but most voip providers seem to cater
for home users who just want to replace their landline. What I need is
probably bordering on wholesale providers. If the UK provider could
arrange the number blocks too, that would be even better. 

Can anyone recommend a provider or providers that would fit the
requirements above, and that plays nicely with Freeswitch?

If you're wondering if this is a toll-bypass voip provider project that
may infringe your own business, don't worry. It's a distributed call
centre business.
