but according to ob rfc, an ua is allowed to register only via one ob proxy (for example in order to save power) in the set, which means that in order to achieve redundancy, i have to setup a passive standby proxy that receives the single ip address if the currently active proxy one fails
Wrong, really wrong. Please Juha check the example in section 9.2:
