Ask HN: Accepting online payments from South Asia

I work for a company that provides cheap international calls. To date the bulk of our customers are from the West, calling Africa and Asia.

Now that we offer services to enable our customers’ contacts to call them back we’ve found one major barrier to adoption there is the difficulty of receiving payments from countries like Bangladesh. Credit/debit cards and PayPal accounts aren’t readily available.

I’ll be asking our users if they have any suggestions, but I was wondering if any of you have any experience accepting payments from these markets?
