That's what I am thinking would be the best solution, but could it be 'many to 1'? IOW, could I have several different extensions all mapped to the same external account, so incoming calls on that account go to the grouped extensions and if any of them ring out, it goes out via that same external account?

Here's another related question. Is it possible to register more than one SIP client to a single extension, or would you just use a different extension for each and set them up in a (hunt) group?

>> Let's say there are 6 SIP accounts to which FreeSwitch is 'registered' and it can make calls using any of them. But which one is used? One of the local extensions (let's say a softphone) needs to receive calls from all of these accounts. This is simple enough and the recipient should see the incoming call information i.e. which account the call is to. But when that extension makes an outgoing call, how can it specify which is the SIP account used to by FS to make the call?

Although one person is dealing with all those businesses, when an outgoing call is made it is imperative that the correct SIP account is used to make that call so that the recipient is correctly informed who is making the call.

You should then be informed which account is receiving a call and can pick a particular account from which to make calls. Once a PBX is in use, you can register the client as a single extension of the PBX and direct calls as appropriate to that extension - I assume with the correct caller ID and incoming account information passed to the recipient so they know as much as in the 'no PBX' configuration.
