UCID-App-ID

The UCID-App-ID SPL option allows the Net-Net ESD to examine ingress SIP requests for the “User-to-User” 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 “User-to-User”.

You must set the value to a 2-byte hex-ascii value that represents the app ID. All input is truncated to 4 characters. Any characters outside the range of 0-9 and A-F will result in an invalid User-to-User header.
