    Hi,
     
    We are working on a caption solution. While my caption/message screen is opened IP phone unable to pass DTMF to called IVR.
     
    Enenthough if services screen is opened during call to IVR, Cisco IP phone unable to send DTMF to IVR.
     
    Is there any configuration at CUCM end for above issue?
     
    Thanks,
    Umesh

    Hi,

    After more test with Cisco IP phone i found that if I open help screen by double click on ? button (7960 phone) after dialing the IVR number then IVR able to accepts digits from phone.

    Can anyone tell me which XML object used to RTP information on 7960 phone?

    Regards,
    Umesh

    Hi,

    I have the same issue mentioned above. My tool sends some text to the screen of the ip phone and if a user tries to send DTMF keys to an IVR system the keys are ignored. Is this because while the push is active the service will trap the DTMF keys? Is there any solution to this? thanks.

    This is the behavior of the phone. Users can clear the service by pressing the Services key and then the digits will go to the call. Alternatively, they can press the line key to bring the call screen up above the service. It is possible different versions of IP Phone firmware handle this differently. This is document in the Contact Center Express IP Phone Agent User guide since that is a Cisco implementation as an IP Phone Service.

    Hi,

    I found a website that offers source samples I used to my project. Check it for help... It is for Ozeki VoIP SIP SDK and helps how to create DTMF IVR sample. This SDK also works with Asterisk and other PBXs. I can recommend it:
