The IP address whitelist/blacklist can be used to blacklist ranges of IP addresses based on the P-Source-Device header in the SIP INVITE. To whitelist/blacklist by IP address, the appropriate header must be present in the SIP INVITE to communicate the information to ClearIP.
P-Source-Device Header
Here is an example SIP INVITE with a P-Source-Device header.
INVITE sip:+18554742536@sip.clearip.com:5060 SIP/2.0
Via: SIP/2.0/TCP sip.clearip.com:5060
From: <sip:+14045266060@transnexus.com:5060>
To: <sip:+18554742536@sip.clearip.com:5060>
P-Source-Device: 104.248.129.175
Call-ID: 123456
CSeq: 1 INVITE
Content-Length: 0
If the SIP INVITE contains a P-Source-Device header, the source IP address is populated in the P Source Device column in the SIP Messages page.
