I have a few Avaya 5610SW phones linked to our Avaya IP Office R8.1 instance that are acting a little funny, and I'm hoping someone here can help me troubleshoot them.
One phone in particular has a "flashing" dial tone when you pick it up (almost like it has a voicemail or something, but there are no voicemails in its queue) and that extension cannot receive any calls - the receptionist has even tried putting the call(s) on park and having the employee pick up the parked call at her desk, but she cannot.
I've reset the phone to factory settings and that hasn't made a difference.
Is there anything else I can try that might fix this problem? I'm starting to think it's something more on the server/software side than the phone itself...
