I was using telephony hardware from Dialogic Corp. The cards were ISA based and handled either 4 or 16 POTS lines or up to 2 T1 terminations. The cards shipped with libraries that had a C-based API and a straight-forward state machine was able to capture the interaction model very nicely. The whole system was implemented in C with a Motif GUI. I think we were using Solaris x86, I noticed that there doesn't appear to be a mention of linux on the Dialogic site. This might be problematic. Perhaps other cards are available, I noticed that the more recent kernels have support for the PhoneJack hardware -- perhaps it can be used for this purpose.
These days, Dialogic offers their QuadSpan VoiceSeries PCI based cards that look like the modern version of the old cards that I was using. I implemented a tight table driven state machine for the interaction model. It was fun and very straightforward. The system was used to call people in communities and alert them of changes in oil and gas drilling operations in their vicinity, as required by law.
You can read more about this at the Canadian Broadcasting Corporation's news service here. There is a bit more information here then at the yahoo article referenced in the original posting. Along with some related site links.
