Dear all:
I have the following questions about SIP B2BUA vs SIP proxy:

1. For service support is B2BUA better than SIP proxy?

2. Is B2BUA suitable to be used as routing entity in the following SIP/SIPT network planning schemas?
    -Hiberarchy structure like PSTN, which has hiberarchied proxies/routing entities. Some one believe
     that B2BUA can be used to substitute call stateful proxy at the edge of such a SIP/SIPT network
    -Flat structure, which has peered routing entities but hiberarched routing database. In this case some
     one believe that B2BUA is even more suitable as routing entity

Thanks!

Sincerely yours, 
Chen Zaifeng
