The problem is that there are also cases where the ob proxies and registrars ARE separated, and what you propose may not be needed in such scenarios. Why don't you simply configure your UA to register each contact with multiple ob/registrar proxies? >also, reliability will necessarily suffer also in complex implementation >when one of the contacts would not be available via more than one proxy. If both contacts are "equal" I don't think that will be a problem. There will be two ways to reach the UA, as if a single contact was used.
