"...anyone who can replace 5ESS features or functions with something else just as reliable."
That's the Problem(tm). Show me a system that is just as reliable, and will be supported (hardware and software) for the next two decades, and I'll jump at it. I just have yet to see anything even remotely close. Until then, I'll take slow and reliable over fast any day of the week.
I agree that licensing fees are getting outrageous, but they're nothing compared to the cost of downtime.
What runs on my 5Ess then? Or Voicemail system? UNIX has had fantastic penetration in the telecom industry, what with being written in large part by a telco, for telco use. (SYSV)
Linux penetration is a totally different story. Unless I see less than 5 minutes a year of downtime, and more than 20 years of hardware and software support for a platform, I can't see using it any time soon.
