[OpenSBC] Is this application feasible?

[OpenSBC F. <ope...@op...>]

Hi all, I am quite new to OpenSBC and I don't really understand if what I would like to do with it is really feasible.


Currently all our users register to a provider's registrar and use its proxy.


I would like to have the users register to OpenSBC, then OpenSBC converts its own logins to remote logins,


so when the users are calling out they effectively direct their calls through the provider's proxy ( in fact, depending


on destination prefix,  we would like to be able to choose between many providers) using their own login, and when


receiving calls from the proxy they should operate in the same way as effectively registered directly.


The purpose of all this thing is solving some incompatibilities in timeouts between UA and proxy, if registrations


are done too quickly they lock up for many minutes, so OpenSBC should keep registrations and give its own to


UAs powering on and off;  then we would like to have many UAs receiving calls at the same time for the same


incoming number, the first one answers, the others then stop ringing.


Thanks for your help.
