Hello Christian,

Thank you for your interest in OdooPBX.
 
We don't have hands-on experience working with Grandstream hardware, so we can't be 100% sure of our modules working correctly with it.

We have two lines of modules at the moment. The Asterisk Calls line of modules ( Asterisk Calls / Asterisk Calls CRM ) are compatible with any Asterisk instance, be it a manually configured Asterisk, FreePBX, Issabel or other PBX system. They are used for integrating the calls with the business processes. The Asterisk Base line of modules are meant to manage an Asterisk instance directly from Odoo. It is meant for working with standalone Asterisk.

Judging by the AMI description from the Grandstream documentation, the agent required for our modules to work (you can see more on the agent at our documentation - https://doc.clickup.com/p/2drb1-197/odoo-pbx/2drb1-302/the-agent) should work with Grandstream. The AMI privileges provided there will allow our modules to support proper call origination and statistics. This means that Asterisk Calls and Asterisk Calls CRM modules will most likely work without problem.

The agent is build with the ability of having direct access to the Asterisk call recordings for sending them to Odoo as well as access to Asterisk configuration for our Asterisk Base line of modules. This means that it's best to have it installed on the same hardware as Asterisk. If that is impossible, installing the agent on a separate place ( for example together with Odoo ) will limit the available functionality to only calls origination and statistics. Asterisk Calls won't be able to receive the recordings from Asterisk and our Asterisk Base modules won't be able to manage the Asterisk configuration directly from Odoo.
