Hello all,

I have a special requirement and just wondering if anyone has any Idea about 
this.

Currently UACs are registering to a VoIP terminator. Account provisioning  is 
done at  terminators network. Client is getting billed for local calls too.

Solution I am thinking of is to build a outbound proxy with local routing 
capabilities.
UACs send registrations to outbound proxy and outbound proxy forwards them to 
VoIP service provider proxy. When 200OK for registration arrives, outbound 
proxy make an entry  in local registration table. It maintains a copy of 
registrations on sip proxy.

When a INVITE is received from UAC outbound proxy looks for callee in 
registration table. If callee is present in registration table, invite will be 
routed locally and if callee is not present  then INVITE will be forwarded to 
proxy.

Is it a good solution? am i violating any RFC rules?

BTW. we are thinking of using OpenSER and modify it according to our 
requirements.


Thanks in advance,

-Sid
