[Serusers] Ser2.0 wrong behaviour of the sl_reply() function?

[tzieleniewski]

Hi,

I am using SER rel 2_0_0 from CVS.
I encountered the following situation.
My scenario was the following:

UA -> Application Serwer -> SER -> UA

1. UA sent an INVITE message to the application server.
2. Application Server changed the Request URI and forwarded statelessly the INVITE message to SER.
3. Everything would be ok but SER replied to the Application server instead of the client. Application server changed only the Request URI and nothing else.
Shouldn't SER sent the response according to the VIA header value??
I kindly ask for Your help.

Below is the ngrep:
192.168.0.112:5060 - this is application server
192.168.0.112:5061 - this is calling UA
