Configuring Your Extension on a Phone
You finally installed trixbox and now you want to set up your extension on a phone and start making and receiving calls. These instructions vary from phone to phone. Basically, whether this is an ATA or an IP phone, you need to get access to the web interface and onto the page where you can configure your sip lines. All settings must match the extension and secret you have created in the PBX interface. Some trixbox supported phones, such as Aastra, Grandstream, and Polycom, can be provisioned remotely with the Endpoint Manager in trixbox CE.
