    We're having some problems with incoming calls that attach to an IVR and then enter extension. The entries are being misread and routing is not happening correctly. For example, a caller may want to transfer to extension 117 and they enter 117 but end up at extension 111.

    The server log shows a potential DTMF error:

    C:341.1: 64.158.162.71:9648 is delivering DTMF using RTP payload (RFC2833). In-Band DTMF tone detection is disabled for this call segment

    Any help on how to fix this would be great.

    Thanks!

    Check that you 3CX box is configured for DTMF RFC2833. You IP-telephones on both sides and 3CX extensions must work with same DTMF RFC2833 method.

    Igor,

    Thanks for the response.

    We're using a SIP trunk from BroadVox. I've asked them how they are handling DTMF signaling. Is there anything that I can do within the PBX to look at or adjust how DTMF tones are being handled between the PBX and the SIP trunk?

    Thanks again for your help.
    Rob
