We have an issue with an elastix 2.3 pbx that is using an HFC-4S card. With the current installation we are having audio issues with our Grandstream GXP 2100 phones. While the call is passing from one to the other we have no audio coming through. We decided then to try a clean install of elastix 2.5 but at this point we cannot find a way to configure the driver for the HFC-4S card.
Any help will be appreciated
