s secs
where s is the number of seconds since SCEP was initiated.
3. If the initial attempt to contact the SCEP server is not successful the deskphone continues
with start-up, and will not try to contact the SCEP server again unless it is reset or
power-cycled.

configuration parameter MYCERTWAIT is 1, SCEP remains in progress until the request for
a certificate is granted or rejected.

least one second, and remains until it is replaced by a subsequent display.

request for a certificate is rejected SCEP: Failed displays on the Title line for at least one
second, and remains until it is replaced by a subsequent display. In this case, the SCEP
server connection terminates and the deskphone continues with startup.

8. If a response is received indicating that the request is pending for manual approval, SCEP:
Pending displays on the Title line for at least one second and remains until it is replaced by

granted or rejected.

the device certificate's Validity object corresponding to the value of the configuration
parameter MYCERTRENEW has elapsed, the deskphone periodically attempts to contact

to renew the certificate, until the renewal request is granted or rejected.
