[Kamailio-Users] uac_replace_from again

[olivier.taylor at gmail.com]

well, I am lost, but not yet drunk.

In fact :

I Ihave a kamailio used to receive calls from an IP with no identification.
I detect the IP, query the DB to know who have to be billed.

Then I use uac_replace_from and also uac_auth to have the caller 
authorisation on the main server.

No problems to setup the call.

the only problem is the hangup when the callee send a BYE, the BYE is 
never forwarded to the caller...


Here is my cfg
