Q: My Polycom / Cisco telephone does not have a dial tone. What can I do?

Answer

If you are using a telephone w/ multiple / shared lines please contact the Service Desk

If this is your desk phone you can unplug the ethernet cable as shown here :

phone port

Reconnect the ethernet cable back to the port with the appropriate data icon:

phone port

Upon reconnecting the ethernet cable, the user will see similar to the following screens:

phone initialize

phone MAC

Please allow the device about 1 minute to return to the normal home screen and check to see if there is a dial-tone.

If you do not hear a dial-tone, please contact the Service Desk via email at help@mit.edu or by calling from another device to 3-1101
