IP Office 500 v2, R8.1(85), POTS lines, and CA buttons. I've got a site in a large metro area with numerous area codes, and the site isn't sure which ones require a 1 first and which ones don't, and they're tired of getting it wrong. How do you configure the IPO to add a 9,1 to all outgoing calls so that the dialer can just dial the number and not have to worry which one needs a 1 and which one doesn't? I assume it's a combination of the ARS table and short codes, but am not sure. Or if there's a better solution, what is it? Thanks in advance for your help.
