I'd like to be able to use the line keys to make a call using another extension. The purpose would be to be able to make outbound calls using the outbound CallerID associated with other extensions. I have several businesses that I make and receive calls for. Having one user extension logged into the phone is fine for identifying who is calling for inbound calls because I can see which call queue they are in when my extension rings. My main problem is that if I want to call a customer, I want to be able to call from the CID that the customer will associate with the business. Any help appreciated. Thanks.
