The company I work for has offices in a mid western state and on the west coast. Right now our phone system will forward calls ot only one number. Currently we have it going to our external switchboard but when that closes at 5:30PM EST the phones switch back to the main home office number. Anyone trying to call for assistance after that time cannot be forwarded to any other number so it goes to a Unity Message system that converts the phone call to an email. Calls for support then go unanswered until the next day.
Is there a phone system or program that will allow the phones to be diverted to our external switchboard during the normal office hours then switch to the midwest or west coast offices until they close. Then it could switch back to the home office number.
