I am lost, and have not found explanations on users, extensions and phone numbers.

We only need one central phone number for incoming calls. Calls are routed to a sales queue or a support queue. We need no specific users. We have a handful of people who answer calls from the queue but do not make calls. Then we have 1 person who might make outbound calls. We have no use for direct dial numbers. We also have a SIP phone that is more community based and occasionally will make or receive a call. We are on standard plan.

Do I need a user license for people with soft phones who do make external calls? These stations are really not named users, but rather a pool that changes. Would that be virual extensions?

Do I need to have any external phone numbers (other than our central number, which does not seem to be billed) ?

It looks like we might have an external telephone number for the community phone. Is this Limited Line ?

Thanks, and pls do not ask me to contact my rep, as I he is out on medical leave, and I would rather have an answer here.
