I just got the ATA187 and have them working. I need to know if there is a way to change settings via a web page? Can't find anything in the online manuals. The part I need to change is turning off the second port. A lot of times we put them next to a fax machine and don't need the second port. I don't want to waste my DLUs.
Unlike the ATA 186/188, the 187 can only be configured via CUCM.
Under, Cisco ATA SIP services
• Cisco ATA configuration through Cisco UCM configuration interface
The ATA configuration has been simplified and streamlined to mimick that of an IP phone. All available options are now on the CUCM page for the ATA.
