    T38 FAX Codec

    normrr New Member

      I have a customer that shares a PRI with a local FAX server and a PBX, about 40 DID's are dedicated to the FAX server.  I am having issues with FAX completion, after many config changes we are going to route the dedicated DID's through a T38 trunk. My question is, in the 904 when I enable Modem pass-through and enable T38 will the codec be used only on FAX tone detection.

       

      voice trunk T02 type isdn

        description "PRI to PBX"

        resource-selection linear ascending

        caller-id-override number-inbound xxxxxxxxxx

        connect isdn-group 1

        modem-passthrough

        T38

        rtp delay-mode adaptive

        codec-list "SIP to PRI"
