  • 1.  Error 223: Bad parameter passed to function when RequestSendDtmf

    Posted 10-28-2015 08:58
    I defined statement below in the coding to send dtmf:
    RequestSendDtmf reqSendDTMF = RequestSendDtmf.Create(thisDN, connID1, numberString, null, null);
    IMessage reqSDTMFResponse = tServerProtocol.Request(reqSendDTMF);

    But I get error 223: Bad parameter passed to function. I've tried to set sip-dtmf-send-rtp = true, but still failed.

    Check the configuration of option "rfc-2976-dtmf"

    Hi Jakub, thanks for your reply. It had no error now, but no dtmf tone when sending dtmf. By the way, I'm using SIP Server version 8.1.101.68
