Implementing Cisco Collaboration Applications (CLICA) — Question 172

After integrating Cisco Unity Express with Cisco Unified Communications Manager Express, users report that the system does not respond to their digit presses.
Which two configuration snippets resolve this issue? (Choose two.)

Answer options

• A. dial-peer voice 6800 voip destination-pattern 5... session protocol sipv2 session target ipv4:10.3.6.127 dtmf-relay sip-kpml codec g729r8
• B. dial-peer voice 6800 voip destination-pattern 5... session protocol sipv2 session target ipv4:10.3.6.127 dtmf-relay sip-notify codec g711ulaw
• C. dial-peer voice 6800 voip destination-pattern 5... session protocol sipv2 session target ipv4:10.3.6.127 dtmf-relay rtp-nte codec g711ulaw
• D. dial-peer voice 6800 voip destination-pattern 5... session protocol sipv2 session target ipv4:10.3.6.127 dtmf-relay sip-kpml codec g711ulaw
• E. dial-peer voice 6800 voip destination-pattern 5... session protocol sipv2 session target ipv4:10.3.6.127 dtmf-relay sip-notify codec g729r8

Correct answer: B, C

Explanation

The correct answers, B and C, specify the use of DTMF relay methods that are compatible with the configuration required for proper digit recognition in Cisco Unity Express. Option A and D specify 'sip-kpml', which may not work effectively in this configuration, while option E uses a codec that is not optimal for the DTMF relay method. Therefore, B and C are the best choices for resolving the issue.
