I need to be able to offer the ability to have my users Dial and "8" instead of a "9" to make a a call as they normally do. By dialing and "8" my user will want to input a specific code before dialing a "billing code" then the number. For example 8-222-404-555-1212. Then I want to send to my sip trunk *99-000222-404-555-1212. Yes I added (*99-000) for my SIP trunk provider.
I could do this easily in an AVAYA phone system. I think this could be done in this NetVANTA 7100 easily but I am not sure where to do this?
I will recommend you start with this link below.
BTW, Have you considered doing something different with the prefix "222". In particular why not add that as part of the DNIS substitution as well, just like you are adding *99-000?
I noticed you opened a support ticket for this issue. The result was adding a DNIS sub on the SIP trunk as well as adding an accept for the billing code (*99) on the associated trunk-group.
