We have three trunks. When making calls, if the call goes out on line 1, no problem. If the call goes out on line 2 or 3, we either get a busy signal with "Busy" in phone display, or "Disconnected" with a fast busy signal.
I've tried everything I can think of. Unused trunks are set to out of service. Disconnect clear is enabled (tried it both ways). The telco has been in and can clip their test phone onto the lines and make calls out with no problem. Lines have been tested OK.
Any ideas?
TIA
