The billing system should use the callid+from-tag+to-tag to match the invite with the bye. Relying only on callid can result on other issues over the times. Forking through a proxy is quite common and specified in RFC 3261.
Anyhow, event there is parallel forking to many branches, only one gets a 200ok -- once one does it, the other branches are cancelled by the proxy.
