Hi,
I have gone through your requirements and create a wrapper page where users can modify their setting through API call.
Pls clarify me the following:
1. To change settings, VOIP user name and password for each user will be required. Is it already available in DB or somewhere else.
Pls PM me to discuss further details.
I have 3+ years of front-end devlopment using HTML, CSS, JS, jQuery, Bootstrap and AngualarJS. I am proficient programmer in asp.net and php also. I can assure you that I will provide quality work in given time period without any issues. The final code will be delivered with comments and documentation.
Looking forward to work with you,
Kasi
