I run a pest control company and it's important that we have emergency afterhours response in that event that a live animal is caught in a trap. I want to create a setup where the user will hear something like "You have reached our office. Press 1 if this is an emergency or wait to leave a voicemail in our general mailbox." If they don't press 1 they're then forwarded to the general voicemail box. If they press 1 they're forwarded to a different voicemail box.
