Device Profile Selection

For help adding devices, please see Add a Device. Use the table below as a reference for which profile to select:

Device TypeProfile
Cisco SPA 303GCisco-303
Cisco SPA 504GCisco-504
Cisco SPA 508GCisco-508
Cisco SPA 525GCisco-525

 

Note: Due to the age of this series, the profile can't be added to new accounts. If the device profile doesn't appear in your administrator portal, the device will have to be added as a Generic SIP device. The device will have to be manually provisioned.

  1. Obtain the IP address by pressing the menu key (looks like a page with the top right corner folded), and press option 9.
