    Adjusting SIP proxy server registration refresh rate

    jvanbortel New Member



      I have an Adtran 908e 3rd Gen that I have a SIP transparent proxy setup on. Everything seems to be working correctly, only I can not seem to set the server registration refresh rate.


      I have the following set:


      sip proxy register rate-adaption

      sip proxy register rate-adaption server-expires 3600

      sip proxy register rate-adaption user-expires 300


      but no matter what, the registration is being sent back to the SIP server every 30 seconds.


      I see the following:


      ADT908E#sh sip proxy registration

                                    - Grant -     Last Server     Next Server        

      User                   Reg  Server   User   Registration    Registration   Flags

      ---------------------- --- -------- ------ --------------- --------------- -----

      xxxxxxxxxx         Yes       30     30 Nov 16 19:11:46 Nov 16 19:12:16  -RT-



      The Polycom phone itself is set to 3600 as a default.  After making the changes to the rate-adaption, I have rebooted both the phone and the router, but have had no luck.



      Thank you,
      Jeremy Van Bortel

          The server expire time can be over ridden based on what the server sends back in the 200 OK.


          Do the following:

          Enter debug sip stack messages


          Then enter

          sip trunk-registration force-register


          then look at the RX 200 OK from the sip  server and at the Expires header. Here is example below, you can see that it is set to 3600, So even if you request 3600, the sip server can over ride it with a smaller value.

              Hi Mark,


              Here is what I see on the debug, the Expires timer is set to 3600, yet I see still the Adtran sending the registrations every 30 seconds to our sip server. My goal is to have the Adtran respond back to the Polycom phones every 300 seconds, but continue to register to our SIP server at the 3600 second rate that is set in the Polycom config.

                  As per our phone call, when proxy wasn’t turned on, 30 seconds would be ok with phones, but when you use transparent proxy, the sip server will need to be changed to 3600 or something way higher than 30 seconds. Then set the phone side to 300 seconds for example.


                  In the debug you send, the server sets the expires to 30 seconds in the CONTACT header:
