Generate and append UCID to User-to-User field
We have a client who sends us UUI information on the User-to-User field on the SIP INVITE.
This information is being forwarded to Avaya without a problem but the SIPREC INVITE sends the metadata info with only the UUI info on the <apkt:ucid> field which causes the recorder to fail as the UCID being sent via SIPREC does not match the one received via CTI link.
We need to find a way to generate UCID on SBC and append it (concatenate) to the User-to-User field that contains the UUI information that comes from our client.
