Ascend Max-Dial
With the MAX DIAL software you can dial out on all 30 or more channels (if you have more WAN lines) with one or more PRI lines on a MAX 2000/4000/6000.
As I know, the Rev 1.03 was one of the last ones we have seen. I will check out what is available on dark sources and will publish it here.
Later on the MAX DIAL functionality was merged with intagy-access or Navis Access software.
But this was advertised really weak and was recognized in late 1999, when the sales was one the way down.
