On-Premises Call Control

An administrator is integrating a Cisco Unity Express module with a Cisco UCME system. A test call is made to the Cisco Unity Express pilot number, but the administrator hears a busy signal. The dial-peer is configured as follows:

dial-peer voice 4100 voip  
destination-pattern 41..  
session protocol sipv2  
session target ipv4:10.1.10.1  
dtmf-relay sip-notify  
no vad

How can this issue be resolved?

  • A The dial-peer needs to be reconfigured to support the G.711 voice codec.
  • B The destination pattern needs to be changed to match the dialed number of 4100.
  • C The dial-peer needs to be reconfigured to support vad.
  • D The dial-peer needs to be reconfigured to support H.323 instead of SIP.
Explanation

Cisco Unity Express requires calls to its automated-attendant or voice-mail pilot numbers to use the G.711 u-law codec. The SIP dial-peer already has the required SIP signaling, SIP NOTIFY DTMF relay, and VAD disabled, but it needs codec g711ulaw so the call can be accepted.
