Dear Sir/Madam,
Thank you for posting your requirement. My name is Inderjeet, small IT services firm at Chandigarh.
You will need to provide credentials to the termination/trunk providers to use the DIDs or channels. We will need root access to the server where it needs to be installed and should not have anything installed already. It will take 304 working days to get completed. Milestone will need to be funded before the work starts.
That should be enough for now. Let me know if you have any questions.
Yours Sincerely,
Inderjeet S Sodhi
