Hey, I am having more than 10 years of experience in Asterisk PBX setup and configuring, and also I had work with similar project where we integrated CRM with PBX solutions. I have confident enough to work with you on this project.
I have gone through your requirements, and I understand that you are looking for someone who can help to Setup Asterisk PABX and integrate with proprietary CRM also, you want web interface to manage DDI routing and ring groups.
Can you please share the API for the CRM? And also would like to understand more on this "An option to switch easily between desk phones and softphones"
Thanks for reading my proposal. Looking forward to hearing back from you soon.
(Note : Proposal amount may vary based on finalization of SOW)
Thanks & Regards,
Arpit
