No Phone Error Message
A No Phone error message displays on the CA50 under the following circumstances:
•
A lost connection between the CA50 and IP PBX.
•
The phone subsystem gets an unexpected extension from the IP PBX. For example, the IP PBX returns an
extension based on the SCCP MAC address.
•
When the phone subsystem is not able to register an extension with the IP PBX. This can occur due to an:
• incorrect IP address
• incorrect port of PBX
• invalid extension
• incorrect password.
•
No free extension is available to be assigned.
Typically when the contact list returns to the CA50, the extension number displays along with the user name. For
users with no phone extensions, only the user name displays.
