Limitations

•In DTMF over SIP mode, if call goes through TPO, values of application.sip.kpml.enabled and application.sip.TPO.kpml.enabled keys for turret and for TPO must be identical. If DTMF must be sent by SIP messages, application.sip.kpml.enabled and application.sip.TPO.kpml.enabled keys must be set to true but if DTMF must be sent by RTP, those keys must be set to false.
