International SIP Breakouts
« on: August 07, 2017, 06:51:41 AM »
Hi everyone,

I have a customer based in the UK with offices around the world. We have just migrated their Paris office across to using the UK controller and have found that they are unable to dial some numbers in Paris which are restricted to being called from the French PSTN only. As they are essentially making an international call from the UK, the calls are being rejected.

Does anyone know of any SIP providers which breakout onto international PSTN networks? We may have a need to do a similar thing for the Netherlands, Canada, and the US in the future so we are looking for a single provider who has breakouts around the world.

Thanks,
Jordan

Jordan, are you sure it's the French network and not the class of restriction? I'm not an expert on international calls but I've never heard of a carrier restricting inbound connections on a wide scale by origin.

Hi ZuluAlpha,

Yeah, it's the network - the number can't be called from any UK mobiles either. I've also tried on our controller as my calls are unrestricted and they don't connect either.

We got the users to test with their French mobiles and that connected fine. It's not all numbers that they have trouble with - it seems to just be premium rate numbers.

If you have trunks on each controller, and your controllers are clustered with IP/XNET it would be relatively easy to send international calls out each respective country's pbx with ARS routing - but that certainly doesn't answer your question.

I personally don't know of any carriers like what you're asking, but that certainly doesn't mean they don't exist.

I think the customer is wanting to move away from controllers at each site, and at some they don't yet have Mitel. Currently they're connecting back to the UK through the MBG.

I have found DID Logic which seems to do what we want but I have the same problem dialling one particular number even through them so I'm not sure.

More testing when I get back to the office tomorrow I think!
