Validate Certification
Chain
Configures whether to validate the server certificate when download the
firmware/config file. If it is set to "Yes", the phone will download the
firmware/config file only from the legitimate server. The default setting is "No".
Sets the phone to broadcast the Multicast DNS (mDNS) message during booting
up to allow itself to be discovered and be configured by the SIP platform. If it is set
to “User Type A’, the phone will broadcast the mDNS message
“A_grandstream-cfg.local”; if it is set to “Use Type SRV”, the mDNS message will
be “SRV_grandstream-cfg.local”.
The default setting is “Use Type A”.
Resets the phone to the default factory setting mode.
Maintenance/System Diagnosis
Select the transport protocol over which log messages will be carried.
• UDP: Syslog messages will be sent over UDP.
• SSL/TLS: Syslog messages will be sent securely over TLS connection.
The default setting is “UDP”.
Configures the URI which the phone will send the syslog messages to.
The default setting is "log.ipvideotalk.com".
Selects the level of logging for syslog. The default setting is "None". There are 4
levels from the dropdown list: DEBUG, INFO, WARNING and ERROR. The
following information will be included in the syslog packet:
• DEBUG (Sent or received SIP messages).
• INFO (Product model/version on boot up, NAT related info, SIP message
summary, Inbound and outbound calls, Registration status change,
negotiated codec, Ethernet link up).
• WARNING (SLIC chip exception).
• ERROR (SLIC chip exception, Memory exception).
Note: Changing syslog level does not require a reboot to take effect.
Configures whether to send the SIP log to the system log server. If check, users
could filter display the obtained log file by setting up the filter condition:
syslog.msg contains "sip log:" on Wireshark.
