Made a conference call from Bangalore, at the Leela Palace, back to a couple people at the home office. $6.50 a minute, which jives with your pricing.
The same time, one of the guys on the team made a bunch of calls from his AT&T mobile back home. Every call was a good 20-30 minutes, twice a day. He (the company) ended up with a $3,000 cell phone bill - and that's with the international plan. Crazy.
