available in three flavors - Standard (last updated: August 31 2010),
Premium (last updated: August 31 2010), and
PSTN (last updated: August 29 2010).
The Standard plan uses the low cost routes, the Premium
plan uses preselected high quality routes, PSTN plan uses routes which connect the calls directly to SS7 network. Standard and Premium rates are updated weekly.
