Product: Hosted PBX 1.0

Tool(s): N/A

LOB Impacted: Voice

 

Summary:

Cisco Desk Phones provisioned on the Hosted PBX 1.0 platform experiencing an issue where they’d display “Checking DNS” and never recover.

 

Process/ Resolution:

 

  1. Connect a computer to the same Local Area Network as the phone. On your computer, open a Web browser and type the phone's IP address in the browser's address bar. You will see the web interface for configuring your phone.
  2. Click Admin Login > Advanced.
  3. Navigate to Proxy and Registration
    • Use DNS SRV set to No
    • DNS SRV Auto Prefix set to No
    • Proxy Redundancy Method set to Normal
    • Save changes and reboot the phone.

 

Cause:

 

The NAPTR records were removed on the HPBX 1.0 Proxy FQDNs. Cisco desk phones need to be set up to do a simple A record lookup, and not a SRV/NAPTR query.
