OneSuite - International Calls, Internet Fax, Call Forwarding User Tips

Have you used a call forwarding service? Well I haven't until recently when I subscribed to OneSuite Forwarding service. You see I always travel in and out of the country. My job requires constant travel to Asia and Europe and I usually activate roaming on my mobile phone before but the high cost prompts me to always look for better alternatives. Mobile roaming is very expensive. Calls at $2 a minute are pretty normal.
