We are going to purchase 24 SIP trunks from a single carrier (Windstream formerly Nuvox). Their sales person is telling me they do not deliver the SIP trunks individually but as one big trunk that is capable of making up to 24 in/out calls at a time.
My problem is this - we currently have tenants that I have configured with different instances of FreePBX. I prefer to keep doing this as we add tenants - each having their own PBX instance. So the question is this ... is there a way to configure an edge PBX using the FreePBX product that will divide up that Windstream SIP trunk into my internal PBX instances? Some tenants have two trunks, some have three, some have six, etc. The next question that follows may have to do with the DIDs too. Some tenants have a one-to-one ratio of DID and trunk. Some have many DIDs and only a few trunks.
So what I am looking for here is what is the best way to do this and a decent link to a white paper or how to on the subject. I am not necessarily looking for step-by-step directions at this time. I am just wanting to get my ducks in a row before we sign an agreement with Windstream.
Any advice will be apprecitated.
