Phones of the Day: Nortel Aastra M5316 and M5008 at the Chicago Public Library

Chicago’s Library system is still on Nortel Centrex. These phones are reliable and easy to use, as many city governments and universities still use these M5000 sets. They look very similar to the M2000 digital sets, but these are in fact, analog digital hybrid sets that only work on a Meridian Digital Centrex or the C-20 from Genband. They have a limited feature set and ring tone selection compared to that of the M2000 series phones.
