If you are working remotely (not at your desk phone) you will need to contact bIT-Telecom for assistance at telecom@berkeley.edu or call us at 510-664-9000, options 2, 1, to determine what type of line you have.

If you are in the office (at your desk phone) check the phone set (you may need to turn it over to check the bottom):

If it says 'Meridian', 'Nortel' or 'Aastra' then you have a Centrex line.
If it says 'Avaya', then you have a PBX line.

If it says 'Cortelco', then you will need to contact bIT-Telecom for assistance.
