If you get EoD when trying to make a call, here are the possible causes.

EoD means Error On Dial – so there was an issue making the call. Normally, this is due to an undialable number. So the first thing to check is that the number being dialled is valid.

If you are not properly connected to the phone system, you will get EoD on every call. So, try a number you know exists – like another extension or the voicemail system. If you cannot get to those, then you need to check your connection to the phone system.

If you need a prefix – like 9 or 0 – to access an outside line, check that is being inserted.

If you open the log file and search up from the bottom for “dial(” you will see the actual number being dialled. Make sure that is correct.
