I have a few questions for anyone using the multi-tenant setup, mainly how to get dialtone to each tenant. If you have a SIP trunk provider how are you trunking each tenant to the provider? Are you giving your server multiple IP addresses? Is there a way to bring in a digital trunk like a PRI into a device and have it shared by multiple PBX's? I would like to host the customers systems in our data center and provide dial tone via PRI's. Just not sure if there is a device out there that will allow for multiple registrations.
