Hello Abu Sayed bhai, My name is Masum, I am also a Bangladeshi, living in UK. I see you have very good experience with Asterisk, and overall VOIP .
I am planning to set up a company for Hosted PBX and Call [url removed, login to view] on Asterisk/Freepbx etc. I would like to set it up in Amazon AWS so that we do not have to worry about the servers.
Will have SIP trunking for the incoming and outgoing calls.
Each customer will have their own portal to manage their users, extensions etc which can be done either with freepbx or if you know of anyother crm can be used.
So..this will be a project from scratch untill we are fully ready to bring in our first customer.
My question to you is, do you think you'll be able to help me with this ? If yes, how much will the whole project will cost?
