replacing existing phone system currently have a fax/phone with two other rechargeable telephones (one at another desk and one in the staffroom) will not be using existing phone/fax machine (dont get hardly any faxes, maybe 2/3 per week and will keep on desk as a stand by) really want to replace phones as one phone isn't recharging very well and also dont have instructions for ansaphone so not sure how to use that either
