Phonebridge Integration with Custom modules

Phonebridge Integration with Custom modules

Hi,
The problem that I am facing is that I am unable to connect custom modules with phonebridge as right now Zoho is limited to only Accounts, Leads, Contacts and Opportunities modules integration with phonebridge.
I created 4 different teams which were focussed on 4 different agendas. These teams could have same leads as their pitch would be different.
So, undoubtedly, I needed 4 different Accounts module and 4 different Leads module for each team.

When I did that, I started with Kixie, but no data was reflected in the custom modules.
Which was a big problem. 
When that didn't work, I tried to integrate zoho with my own "PBX Sangoma"

The integration was done rather easily on PBX Sangoma, but still Zoho was unable to connect with PBX Sangoma too. I have no idea why. Although it shows that PBX Sangoma is a connected app in my Zoho CRM.

I am not sure what to do next. How to get my team start calling from Zoho CRM itself?
Any suggestion or any help would be very beneficial.

Thank you.
