UC540W, SPA504 & SPA500 DS

[isiconsultants]

Extension listing is not showing up in digital format on a SPA500 DS, which is connected to a SPA504; has anyone gotten this to work?

I told the customer to write the usernames/extensions on the display with a non permanent marker for now; kinda embarassing

I'm running a UC540W with the latest service pack, etc.  Please help

thanks,

Hector

Hi,

Are saying that the buttons are programmed and actually work correctly, but there are just no display names?

Hi Hector,

Unfortunately at this time the SPA500DS is not supported on UC540/UC560, only the SPA500S. The SPA500DS is only supported in SIP mode.

Based on the Session Initiation Protocol (SIP), the Cisco SPA500DS has been tested to ensure comprehensive interoperability with equipment from voice over IP (VoIP) infrastructure leaders, enabling service providers to offer competitive, feature-rich services to their customers.
