GUCID-Node-ID
The GUCID-Node-ID SPL option allows the Net-Net ESD to examine ingress SIP requests for the Cisco-GUCID header. When present, the header is transparently passed through the egress SIP message. If set to replace-ucid or the header is not present, the system generates a new value for Cisco-GUCID.
You must set the value to a 48-bit node ID in the version 1 UUID defined by RFC 4122. You can enter the value in decimal or hexadecimal notation. The value must be prefixed with 0x when hexadecimal.
