I am installing a 6940 on a Mitel 250. The phone works but I get an error saying "cannot display" What does that mean? Also, I can't get the keymap to populate on to the 6940. In the Phone Manager it does show that the keymap is assigned to the phone. Any help would be great.
I have a Mitel 400 using Analog and SIP phones. When I make calls to 911 on the SIP phones the 911 operator can not hear me. Two way speech path works on the Analog phones. I'm using a PRI. Any suggestions on what the problem could be. Could the 911 system not be receiving the proper CLID?
