The 183 response sent establishes an early dialog. Any request which generates 4xx response should terminate the dialog i.e the UAC sends a BYE to terminate the dialog. Rahul
Hi, I have one doubt. Take a scenario where A calls B. B sends 100 Trying and 183 Session Progress to ingress side. The ingress side sends PRACK in response to 183. Now B sends 4xx in response to PRACK. Now what happens to the PRACK and what response sent to the INVITE request from A. Please find the call flow if you need.
