Hi All, I have a following situtation: Sip-Endpoint --> Opensips B2B (with REFER scenario) --> Opensips Proxy(Using Proxy Authorize for Authentication) --> PSTN Gateway
I need the "B2B Opensips" in between so that it can handle the REFER requests properly. The problem is that the "Proxy Opensips" responds back as 407 with Proxy-Authenticate header along with the realm and nonce value; but the "B2B Opensips" would only send the 407 response to the Endpoint without any Proxy-Authenticate header. Thus the call fails. I cannot authorize the Sip-Endpoint on the "B2B Opensips" because of the limitations of my architecture. What I need is, the 407 response gets back to the Sip-Endpoint transparently and the response to the same also reaches the "Proxy Opensips" properly, so that the proxy authorization becomes successful and the call can go through properly. Is there something that can be done on the b2b_response route? Any pointers or directions in achieving this will be very helpful !! Thanks in advance. --- Jayesh
