DTMF, thanks, can you tell how old this system is. the serial # is 73245
Can you tell me how to default this and will that eliminate the DSS ports?
Right now there are phone sets connected to these ports and they seem to be working but
many don't ring.I figured it was something in the ringing assignments. All the phones are
6620 PG. Can I program with this or do I need
a display set?
How do the ports correspond to the pairs off the amp connectors? Are Manuals still available? Thanks again.
W.A.M.
