Ok again here is the latest response I got back from ZOHO regarding this issue. What specifically can I ask them so as to get clarification on what they need? I know the FreePBX developers time is valuable and I am willing to pay for that time. But I have been going around in circles since October 2016 trying to get this to work…
Thank you for your patience,
I have discussed about this issue with all my senior developers and their managers, the issue seems to be only with the channel settings on your Asterisks server which we do not have control over this.
We have lots of clients working with the same Phone bridge adaptor without any issues, since the channel information on their servers are configured properly. We have provided you all the required information to contact a PBX developer to change the server settings and we do not have anything more than this to perform any changes from our end.
I would request you to contact the Asterisks support team to setup the proper channel settings on your Asterisks server. I am sorry again, that we will not be able to provide any support regarding this issue from our end, since all the required information has been given.
Feel free to write to me, if you have any further questions about the applications in Zoho CRM Plus subscription, so that I can assist you accordingly.
Looking forward to assist you.
