[cisco-voip] [External] Re: ATA Devices

Sort of a derail, but years ago we tested grandstream and audiocodes devices to replace the ATA-186. We weren't on 11.5 then and ultimately didn't implement either.

Devices that provision as "basic" SIP devices in the UCM haven't been any trouble for basic features. Both devices worked for very basic calls (make, receive, hold, resume, CLID) without any trouble. Configuration is pretty static on these things once set, so assuming you could upload one, or serve one via TFTP/TR069, a boilerplate isn't too bad, but it does take up some time. At least in our environment we don't reconfigure these often as they're for fax machines, alarms, etc that don't move.

If I recall in testing other supplementary services either didn't work or were setup for Broadsoft URIs that aren't supported. I still use Grandstream personally and haven't had any issues with them. The audiocodes device I wanted to shotput into a lake as it was horridly complicated to setup for this class of device.

In both cases it's been quite a number of years and the product landscape may have changed. VG204/310/320/etc administer differently and had other considerations for third party devices at this scale on how they'd either register ports or be trunked to which, as Lelio says, we didn't have the resources/cycles to put to  that versus the cash at the time.
