    Issues with Transparent SIP Proxy

    cahollow New Member



      I'm using a Netvanta 6355 and working on setting it up as a transparent proxy but when I have the configuration in place that I copy from here: https://supportforums.adtran.com/docs/DOC-7023?q=Issues%20with%20Transparent%20SIP%20Proxy  the phones will not register.  Below is are pertinent parts of the config..  I will see the phones show up when I do a "show sip proxy reg" but show as unregistered.  The primary issue right now is that when I have this config in place, the phones cannot register with our PBX through our SBC, I have to disable sip proxy before registrations will work properly.

          I ended up opening a case with support and it was found to be an issue with how the Yealink phones (also one model of Grandstream I tested) responded to the SIP 407 Proxy Authentication Required message they were receiving from the Adtran.  The phones never resubmitted their register request with the credentials, just continued to send in register requests without them.


          Because of this I ended up going a different direction than the SIP transparent proxy feature (phones are registered to the PBX AND to the Adtran on as a secondary SIP server for survivability).  So this can be marked as completed/answered
