Not sure if this is the right place to ask this, but I wanted to get the right eyes on this question.
Windows Server 2003 - Dell Poweredge. We have a data provider that still lives in the stone ages and exchanges data over a dialup modem. The problem is that each request/response takes on the order of 15-20 seconds and our volume is getting to a point where we need multiple lines. What options are there? In the age of VOIP, I was hoping we could do this over a network card, and use a half dozen virtual phone numbers to send out our requests. Otherwise, it looks like we'd have to find a multi-line modem. Any ideas?
