Sigma Voice uses 6 second billing like most large telecom carriers and providers.

Other automated dialing services may offer a rate in the form of a "credit" using 30 or even 60 second billing increments. 30 second or 1 minute "rounding" increases the total overall cost drastically on these short duration phone calls.
