Supported telephone sets (Meridian and Aastra business sets and single line sets) and all telecom peripheral equipment such as Audio Conferencing Units, Head Sets, can be purchased from a number of online vendors. While departments are free to purchase supported equipment from any vendor they choose, Telecom Services has provided links in the Phone Set Catalog that you may click on to see current pricing from recommended suppliers and to place orders directly. Orders should be carefully coordinated with service order cutovers. Telecommunications is happy to answer any questions you may have about the various phone sets that are available depending on the line type in question. Telecom Services cannot guarantee that all features (e.g. message waiting indicator) will work if departments choose to purchase equipment that is not listed in the UofT Phone Set Catalogue.
