| What about the alarm systems Anyone in the security industry will tell you that VoIP anywhere in the path from premise to monitoring station causes failure. Yes, there are IP communicators, but that doesnt change the fact that 99% of the installed base of security systems still uses POTS.
With requirements to have fire systems and monitored sprinkler systems in most commercial buildings, there is a massive installed base of POTS based systems and it's growing. The fact is that most AHJ's (fire marshalls) still insist on POTS lines to the fire systems, and they hold the final word in granting a certificate of occupancy. |
