No memory after a Software Update
In some cases "No memory" is displayed after an application download
Æ page 138.
• Restart the phone Æ page 144 to free up memory.
• Perform the software update again.
If "No memory" is still displayed:
• Save the current configuration Æ page 76.
• Restore the factory settings Æ page 98.
• Re-enter the minimal set of IP Æ page 48 and FTP Æ page 75 param-
eters.
• Perform the software update again.
• Restore the saved configuration Æ page 76.
Security
Payload not Encrypted
The payload between two optiPoints is not encrypted (no lock displayed on
the screen).
1. Check whether the phones have the current time. The use of a time
server is recommended for this.
2. Check whether the phones use TLS as transport protocol.
TLS Authentication Failed
"TLS Authentication failed" is displayed on the screen. A possible cause is
that "SIP server validation" is activated but no certificate is installed on the
phone.
No Registration with Line Keys
A line key does not register when digest authentication is activated
The reason for this is that realm ID is required to be registered with the line
key from V7.
