James, The realm/service selection name is generally more relevant to IPStream or WBMC Shared (as per SIN471) rather than WBC. The issue you are facing is that the selection of authentication infrastructure is done on the subscriber <-> CP mapping - such that there is a tight coupling between the RADIUS authenticating the CP and the forwarding context that the authenticated user is placed into. WBC will determine the CP that the line belongs to, and then request RADIUS authentication from that particular CP’s RADIUS. Since this is the case, then your BT Business -> other CP migration is doing what is expected — authenticating with the BTB RADIUS infrastructure, rather than your own since the RADIUS is selected on the calling line ID (not the authentication details - which WBC passes transparently). The same is true with WBMC Shared CPs, the “owning CP” is identified, and their RADIUS infrastructure is consulted for authentication until such time as the migration has completed. In the WBMC Shared case the SSN is used to differentiate different behaviours required for different sets of EUs of the same CP. The potential means to ease your migration path is to ask the owning CP to act as a proxy RADIUS for the lines that you are migrating to your own infrastructure (although, this of course requires co-operation of the existing CP for the line) — such that your authentication details are valid for the subscriber on both sets of infrastructure; or alternatively determining a means to authenticate these lines without checking the PPP authentication credentials on your own infrastructure (for instance, an access accept that is based on the SID (BBEU/FTIP/BBIP…) — meaning that once the line is migrated, then your infrastructure still authenticates the user, regardless of the PPP username/password that is configured. Hope this helps — if you need further assistance with this matter, then I’d recommend giving your BT Wholesale account team a shout to determine whether there is anything else that might be able to be done to ease the path.
