Hi Experts. I have 4 digit extension numbers beginning with a 2. Callers know the extension numbers so I want to offer 'if you know the extension number enter it now' on the automated attendant of the IP Office Essential Edition. I also want to use single digit numbers to route to some extension numbers (i.e. for xxx press 1). So my question is, with the Essential Edition, can I use 2 for routing to a specific extension or can I not use it because my extensions begin with 2? Thank you!!
