Hi All, Could any one please help me out on requested queries as below: 1. How to handle a duplicate 407 or 401 messages received. 2. How do we identify the received message is a duplicate message. 3. Is there any specification to handle a duplicate messaging.
The scenario is as follows: UAC Proxy *************************************** INVITE---> <---- 407 for Invite INVITE with Auth ---> <---- 407 for Invite ( before receiving INVITE with Auth) <---- 200 OK Proxy re-transmits the 407 duplicate message before receiving INVITE with Auth. UAC received the duplicate 407 response after sending INVITE with 407.
