[Freeswitch-users] Account selection

[Ken Gillett]

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?

This can be very important when each SIP account represents a different company/business. 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.

Currently (no PBX), my softphone registers to each of these 6 accounts and I can choose which account to use to make a call. But if I am registered to FS as a single extension, how can I tell FS which account to use when I place an outgoing call? Is there any way to do this without having to use Dial plans?

>> If one wishes to have use of several VOIP 'lines', but with no PBX, you need to register all those SIP accounts with the client (softphone etc). 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.
