This feature supports A/AAAA queries only. Ensure that the SIP Trunk Group services parameter dnsSupportType is set to 'a-only' when using this feature (see SIP Trunk Group - Services - CLI). |
...
The filterSipSrc object allows only those SIP messages originated from source to appear in the list of learned/resolved IP addresses from configured FQDN entry.
...
Use the following CLI syntax to force the SBC to query the external DNS server for the selected FQDN entry
...
. This request essentially instructs the SBC to ignore locally cached records and perform an external query
...
to the configured DNS server.
