Summary

Accordingly, this preliminary analysis finds that the traditional premise-based PBX PS/ALI tariff service installation cost varies range from $12.35 to $18.14 per user and monthly costs vary from $1.48 to $1.95 per user, for a 100 station implementation. The traditional PBX PS/ALI solution also requires staff time to monitor and update the PS/ALI database when there is are moves/adds/changes. For a 1500 station IP-based enterprise MLTS, the cost ranges from $4.67 to $39.95 per user, but updates to the PS/ALI database would be done automatically by the software.
