Integration with Asterisk PBX server

I have a requirement to integrate ERPNext with Asterisk PBX server. I need to integrate it with the Issue module.
Please let me know if this is possible and if it has been done earlier.

It is possible but has not been done earlier, you can send a Pull Request and contribute.

Is it possible to raise funds for projects like these ? I believe there are a lot of people willing to fund projects like this. Erpnext foundation could have a separate funding projects store organized according to the nature of the project .

For feature and project funding there is this option https://discuss.erpnext.com/search?q=erpnext%20bounty
