Hi,
I want to disable DTMF for agents when the agent transfer call back to IVR. I tried it by disabling the DTMF using SIP trunk but in this case caustomer is also unable to provide DTMF. Moreover with SIP normalization we removed telephony event in the SDP message but it only works for SCCP phone and I am having SIP phone.
By default SIP phone is using KPML to send the DTMF. Is there any way to block the DTMF in KPML.
Please advice is the any other way to achieve the requirement.
Thanks,
Ashfaque.
