Thread: IP line extensions call quality

  1. #1

    Default IP line extensions call quality

    Hello, I have a following scenario

    Router with WiFi and DHCP server to which Quadro 16x is connected.

    Quadro has both Wan and Lan ports configured and has global and local ip numbers put in. IP phones can only connect from local network.

    I have enabled 2 IP lines on Quadro and connected them to extensions 32 and 33.

    I also have 16 PSTN analog phones connected.

    When I want to make a phone call between extensions 32 and 33 the call quality is usually very bad even though both IP phones (I use iPhones with Bria software) are on the same local network. Bria's network quality indicator shows poor network quality.
    When I call PSTN PBX extension the call quality is usually good (I do not remember if I had bad quality here).

    Please advise me what I can do about this, do I need to set-up router in some way, or is there some configuration I need to set-up in the Quadro?

    Change the codec support on the extension to be in line with the codecs used on the Epygi to the Bria software - extensions management -- extension codec to the right of the extension.
