phones rings but no voice path

Hi,

I followed instructions in CCIE Voice Lab Workbook.  All BR1, BR2 and PSTN phones rings when called, but no voice path.  All my GWs are "MULTIPLE_FRAME_ESTABLISHED".  No DSP errors.  GW routing checked, all ok.  I cannot find any doc/URL to troubleshoot this scenario. Can anyone help?

  • Jake:

    Can you tell us which lab you are working on? Is this on one of the graded labs racks?
    To verify your issue - you are getting the call setup ( i.e. proper phone rings ) but no voice is being heard FROM either phone?

  • Hi,
    I'm working on CCIE Voice Value Training Package #2. Yes all phones
    ring but no voice from either/any phone. I attached one more PSTN
    phone, and local calls on the same PSTN CME GW are ok. Thanks much
    for checking.

  • Hello Jake,

     

     

    Have you tried using the debug voip rtp packet command yet? Try this once you place a call, and let us know what the output if any is. Also, you can use the debug voip ccapi inout command to look for errors in the setup or call path.

     

    Hope this helps

  • I appreciate all the help Josh. Attached are the debugs, I called
    911 from HQ to PSTN. I do not see any error or failures from logs
    Thanks so much...

  • Hello,

     

    Unfortunately the attachments are not attached. If you can paste the ouput into a response, or send to me directly at jfinke at ine.com I can take a look at the debugs.

     

    Thank You
