I have such requirements. In providing sip-based residential ip telephony, I would like to restrict each home subsriber is only allowed to register one UA per account. This would make easy for billing purposes and for security reasons.
Is there a way to achieve this requirement with SER?

you can base billing on the username/realm in Proxy-Authorization header. that way your user can have any number of uris and for each can register any number of uas.

Honestly I do not think that such a restriction makes your network more secure. As long as the user knows correct username and password, why don't you let him to register several user agents ? Such a restriction would not allow simultaneous use of user agents with different capabilities, like voice-enabled-only phones and IM-only clients. Or do you expect your users to switch off the phones and start their IM clients if they want to send an instant message ?
What kind of problems do you expect when billing several user agents of a single user ?
As I have written already, it is not possible to do such a restriction with ser.
