  • Seems so many issues you are facing in your voice network. Let me try if I can help you.

    Regarding the 



     1. Call History issue - please make sure HTTP/HTTPS ports are open from IP Phone to UCM TFTP Server.
     2. Delay issue - please be specific. Delay while talking from phone to phone? Or delay while ringing? Please brief your network. Did you check the latency from phone to phone and phone to UCM?



     3. Echo issue - there are certain scenarios. Please check this document and find the exact scenario and resolution: http://www.cisco.com/en/US/tech/tk652/tk698/technologies_tech_note09186a0080149a1f.shtml

  • Echo problem is in whole company. Many User face it some times.

     

    Delay is while transferring the call n while speaking in some calls.

     

    Call history cannot be shown due to firmware ???
