[OpenSIPS-Users] UPDATE with SDP after 183 Session Progress, allowed?

[Vlad Paiu]

Hello Saúl,

Not even now, in 1.8, the dialog module does not call the 
DLGCB_REQ_WITHIN for requests in a dialog that's in early state.
The only exception is the PRACK.

Regards,

The SDP doesn't get changed which causes the other side to think it can send the media straight to the ACME Packet SBC while both sides have to send their media to/through the proxy. We see the SDP is changed in UPDATE messages but not in this specific situation (UPDATE between the 183 Session Progress and 200 OK for INVITE).
