• PKCS#12 file format is supported for installation.
To check the number of days remaining for Identity certificate expiry, use the parameter
CERT_WARNING_DAYS . The user is notified through a log message if the log level is
maintained as WARNING with the category CERTMGMT. The logs are maintained and displayed
if SYSLOG is enabled.
MIB object tables and IDs are created for certificates installed on the phone. You can view the
certificate attributes through an SNMP MIB browser.
To implement DES, the phone has 64 Public CA certificates built in. For a list of the certificates,
see Appendix B.
Phone identity certificates
Identity certificates are used to establish the identity of a client or server during a TLS session.
Phones support the installation of an identity certificate using one of the following methods:
• Secure Certificate Enrollment Protocol (SCEP) by using the 46xxsettings.txt file
parameter MYCERTURL.
SET MYCERTURL "http://192.168.0.1/ejbca/publicweb/apply/scep/pkiclient.exe"
• PKCS12 File by using the 46xxsettings.txt file parameter PKCS12URL
SET PKCS12URL http://192.168.0.1/client_$MACADDR_cert.p12
Note:
If both MYCERTURL and PKCS12URL are provided in the 46xxsettings.txt file, then
PKCS12URL takes precedence over MYCERTURL.
The attributes of an identity certificate can be viewed by using a MIB browser. The following MIB
OIDs can be used for this query:
Attribute Name MIB OID
Serial Number endptIdentityCertSN
Subject endptIdentityCertSubjectName
Issuer endptIdentityCertIssuerName
Validity endptIdentityCertValidityPeriod
Thumbprint endptIdentityCertFingerprint
Subject Alt Name endptIdentityCertSubjectAlternativeName
Key Usage Extension endptIdentityCertKeyUsageExtensions
Extended Key Usage endptIdentityCertExtendedKeyUsage
Basic Constraints endptIdentityCertBasicContraints
Server certificate validation
A server always provides a server certificate when the phone initiates a SIP-TLS, EAP-TLS or
HTTPS connection.
