This is a strange one.
Incoming calls appear to be OK and so do Outgoing calls to area codes that are not our own, but those that share our area code appear to not be connecting properly.
The first indication on a local area code call that something is different is that there's no ringing noise after the number has been dialed. All there is is silence. You can't here anyone and they can't hear you.
When you get a call back from the person you were calling they tell us that when they answer the phone all they hear is silence. So the calls are getting through to local areas codes but the audio isn't, neither side of the call is hearing anything.
Calls to numbers with a different area code and mobile numbers both work though. It makes a ringing sound prior to connection and then they answer, as normal and expected.
So, for some reason calls to our local area code aren't working properly, and seemingly only them.
Summary:
Mobile calls: WORK
Local Area Codes on Landline : DOES NOT WORK
Other Area Codes on Landline : WORK
Voicemail : Can reach and apparently works
I've turned handsets and phone base stations off and on, and also rebooted the router, as our landline now requires that, and nothing has changed.
