I currently have 4 staff sharing 2 BT feature lines (+we have a fax line on separate bt contract that is not a part of this equation) I would like to be able to: Pay less on line rental if possible! Transfer calls internally Make outgoing calls while the primary number is in use Not have customers get an engaged tone Any suggestions please? Or recommendations for a company to try? I don't mind payi out a little bit if new hardware is required to do all this, but im sure there must be a better way than having multiple hand sets on desks and passing phones! Many thanks!
