Hi, I have 18 years of experience in VOIP and asterisk. I offer my services for your project. Please have a look at my profile to see all my experience details. I assure you of a high quality professional service. We can chat out details.
Depending on the work you need is the time it will take, if you require any explanation you may have to write and I could deliver it quickly and if it is wide it would take a few hours but maximum 2 days
