We have repurposed a couple of 7912 phones and have them all set up. but when we deployed them, they will show User/Extension and shows caller id, but when user picks up to answer, there is a busy signal on the caller phone and nothing on the user phone! These phones were working prior to repurposing them. Any ideas?
Thanks for your reply, what we basically did was change the extension of these two phones to another extension and bldg. We did not change anything else. These phones worked fine before we made the switch. Since I am not the one who set up the phone system, that tech is long gone. I am trying to do this without any documentation. I imagine you mentioned GWs would that be gateways?
Trying to use the phones on internal connections is not working. the caller gets a busy signal and the receiver gets a no connection sound. No dial tone or anything. Just as if no one is there.
