[OpenSER-Users] Reg. Proxy authentication

[Padmaja]

Hi all,
Please see the call flow below:

GW1                        Proxy                    GW2
|-----invite----------->|                             |
|<------407-----------|                             |
|-----invite w/cred--->|                             |
|                                  |-----Invite------->|
|<------------200 Ok---------------------|
|----------------Ack--------------------->|
|                                                                |
|                                  |<----ReInvite -----|
|

When the proxy receives the Reinvite below from GW 2, should it again 
challenge it for proxy authentication or simply forward the call to the GW1? 
The openser proxy in our lab simply forwards the Invite without asking for 
authentication this time. However, I need to test the situation, where the 
proxy asks for authentication for the Reinvite. Is this possible?

Please let me know.

Thanks,
Padmaja
