    Outbound calls occasionally receive fast busy signal - Please give any suggestions

    spza New Member

      I recently began working for a small family-run business where the Network admin had left abruptly, and I inherited his mess. Throughout the quest to fix the problems he left for me, there has been one issue that remains unsolved, and that is that all polycom 706 phones on the network will get a fast busy signal when dialing to an outbound line about 15% of the time. So while most calls go through, for no real obvious reason some won't. I have researched this extensively and tried everything from increasing the timeout for the UDP ports, to forcing the phones to register before making an outbound call.

       

      I have rebooted the 7100 many times, and next I will be upgrading the firmware to the latest extended release version available. However I am being told that will not fix the problem (even though nobody can tell me what will).

       

      Has anyone encountered this before? Is there any advice anyone has for me in this situation? If someone really wants to dive into my config I will oblige, but I do not want to create large amounts of work for anyone, I was hoping that someone ran into this in the past and could steer me in the right direction.

       

      Many thanks,

      Jon

          I updated the latest firmware this afternoon, but the issue still exists. I had a period of about 15 minutes with no incoming/outgoing phone calls to try and find any pattern to when the outgoing calls fail, but nothing, It could be the first try, it could be the 5th try that fails, it could fail twice in a row, it could connect 6 times in a row (rare).

           

          There is no record of the calls that fail. When I look at the call activity it only shows the calls that connected.

           

          Here is the config:
