Hello all I am looking to find out from users about voip on cloud, especially FS on Amazon EC2. Google gave very few results. There were very few positive posts/articles, among them Eric Wickstrom's post on this list around 2009<http://www.spinics.net/lists/freeswitch/msg03870.html>but many seemed to be having clock/echo related problems. I would like to ask if any of you are successfully using Amazon as a voip hosting provider & what are the issues involved/stumbling blocks. I am looking to install a sme multi-tenant production system and will be selling voip minutes to a small focus target segment. I am mostly a marketing man & a small-time hobby sys-admin, so I'd also like to know how difficult it is. On a side note, I would like to solicit your opinion of Sipwise free & pro edition <http://www.sipwise.com/products/comparison/> especially with respect to deployment on Amazon cloud. With best regards & thanks. Sanjay.
