A Cisco voice gateway connects to a SIP trunk that only supports DTMF relay via RFC 4733 with payload type 101. The gateway's default configuration uses in-band DTMF. Users report that IVR menus on the SIP provider are unresponsive. You need to ensure DTMF is correctly relayed to the provider. What should you configure on the voice gateway?

Set the DTMF relay method to rtp-nte and configure the payload type to 101 on the VoIP dial peer.

Configure a codec preference list that includes G.711 and set the payload type to 101.

Use the 'no dtmf-relay' command to disable DTMF relay and rely on in-band tones.

Enable 'dtmf-relay sip-kpml' on the dial peer to send DTMF as SIP INFO messages.

What is the purpose of using DNS SRV records for voice gateway call routing?

To specify the DTMF relay method for a call

To provide server discovery and redundancy

To define the codec preference for a call

To set the destination pattern for a dial peer

What is the purpose of a codec preference list on a Cisco voice gateway?

To specify the DTMF relay method for a call

To set the destination pattern for a dial peer

To define the order in which codecs are preferred for negotiation

To define the session target for a VoIP dial peer

Which DTMF relay method carries DTMF tones as named events within the Real-Time Transport Protocol (RTP) payload, as defined in RFC 2833/4733?

Out-of-band DTMF relay using RTP telephone-event packets
