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.
