I'm almost positive I can add some sort of adapter or other hardware in between the incoming VOIP lines and the PBX to make the PBX think they are normal phone lines.
Anyone help me out with this?
One correction I am assuming you are in the USA.
If that is not the case ignore everything below as I know nothing about foreign countries.
there is NO difference between VOIP dial tone and POTS dial tone unless you have a GROUND START system. Really old, not real common [except pay phones], really annoying, not compatible.
If you do not have a ground start system, the only time you will know is if something is wrong with your VOIP/internet service. In which case, it be the same as if something was wrong with your POTS service.
The trick is knowing where your current providers lines run to meet YOUR system, usually a punch down block system of some sort, what interface system your VOIP and PBX systems support [RS-232 versus RJ jacks versus IDC for the actual UTP [usually cat 5 these days] pairs, and the tools you will need to work with it [all are available from lowes/home depot like stores these days but you still need to know what they are and how to use them].
AVAYA is a fairly new company that spun off Lucent who spun off AT&T back in the day and unlikely to even have a ground start system available as they were DOA long before they existed as pay phones started to disappear in our society. Your current phone company should know what you are paying for and you could ask them your IT guy should also know what kind of system you have so you could ask him.
