Zoho and FreePBX integration with CRM Link commercial module

Hi Zoho Team,

We have recently purchased the FreePBX CRM Link module for Zoho running Asterisk 13. API is connected and user are been synced but call are not working.

We have followed this guide: https://wiki.freepbx.org/display/FPG/Setup+for+ZohoCRM, There isn't any additional documentation about it.

API status show connected but when I try to call a Contact from Zoho, call doesn’t work (only show Connecting…). Already tried creating a new contact with a internal extension (registered at freepbx), then calling that extension, but not luck.

Do I need to install Asterisk 1.4 PhoneBridge? Is there any additional step?

At Zoho, Setup-> Channels-> Telephony: FreePBX is not listed. Why not?

Thanks
