Just a few points I'd like to add:
Qwest's dynamic IA T1 (and other carriers that offer a similar product) use VoIP for the voice lines, instead of dedicated TDM circuits. Which is how they get away with being able to offer a full 1.5M of data in addition to multiple voice lines (as many as 24).
With Qwest, each time a phone is being used, about 96k of bandwidth is removed from the total. Kind of high compared to some other carriers I work with, which only need about half that due to stronger compression.
The main advantage of dynamic T1s are cost savings, such as: flat rate local calling (especially helpful if you live in a monopolized area where the LEC charges for EACH call whether it's long distance or local). Also, if your office needs 6 or more lines, plus business grade internet access, it's more economical to use a dynamic IA T1- rather than a separate data T1 and 6 POTS lines. That being said you should always retain at least one POTS line no matter what, for emergencies, etc.
A MAJOR advantage for businesses with multiple locations is the ability to call between them for FREE, assuming each site has one of these dynamic Ts installed...

Being heavily involved with Qwest and selling and installing many of the IA circuits, which Qwest calls One Flex. I have seen the good and bad from this product. The good is it provides a dedicated internet circuit for cases where DSLis not available or the customer wants something better then DSL but doesn't want to pay for a full T1 for IP and seperate voice lines. Also since this is a dedicated type of service the response on repair issues is wonderful.
The bad on this product is that faxes/CC machines actually work much better over an analog line and not this. Normal CC auths work but batch procesing seems to fail on busy days so it seems as if big faxes or big data transmissions fail. Also lately it has had a few bugs such as people can't hear the caller but the caller can hear them. All those kinds of issues get repaired real quick though it seems.
I would recommend One Flex for anyone that wants better then DSL or can't get DSL and needs more then 6 analog lines but less then 13. It can be delivered to the customer as PRI or analog lines and the dialtone is just like a regular analog circuit. Yes the calls do take a portion of the circuits bandwidth but only noticeable if you have the full 1.5m internet and 13 lines.
