A SIP Filter Profile is a collection of the configurable filter settings of individual SIP headers. Depending on the filter settings of each of the SIP headers in the SIP Filter Profile, the SBC either relays the SIP messages without parsing the header, or parses the headers of the messages.
...
| Info |
|---|
- In the SIP Filter Profile, the default filter setting of all the headers is
disabled. To filter a particular SIP header, change the setting to enabled. - The SBC supports attaching a SIP Filter Profile to a SIP Trunk Group. If no SIP Filter Profile is configured for a SIP Trunk Group at the time of its creation, the default SIP Filter Profile is attached with the SIP Trunk Group.
- Even if the filter setting for an unknown header is set to
disabled, the SBC transparently relays the SIP messages containing that header in the following cases:
- The flexible header transparency indicates that the particular header should be transparently relayed.
- The IP Signaling Profile indicates that the particular header should be transparently relayed. To transparently pass all unknown headers, set the transparency of the unknown headers to
enabled in the IP Signaling Profile.
