Verifying Basic Cisco Unified SRST Multicast MOH Streaming
Use the following procedure to verify that multicast MOH packets are configured with the
multicast
moh
command.
SUMMARY STEPS
1.
debug ephone moh
2.
show interfaces fastethernet
3.
show ephone summary
DETALED STEPS
Troubleshooting Tips
The
show ephone summary
output should show a file type as either .au or .wav. If INVALID appears,
an error exists.
Router#
show ephone summary
!
File music-on-hold.au type INVALID Media_Payload_G.711Ulaw64k 160 bytes651-

Command or Action
Purpose
Step 1
debug ephone moh
Example:
Router#
debug ephone moh
!
MOH route If FastEthernet0/0 ETHERNET 172.21.51.143
via ARP
MOH route If Loopback0 46 172.21.51.98 via
172.21.51.98
!
This command sets debugging for MOH. You can
use this command to show that the
Cisco Unified SRST gateway is multicasting MOH
out of Loopback 0 and Fast Ethernet 0/0.
Step 2
show interfaces fastethernet
Example:
Router#
show interfaces fastethernet 0/0
!
30 second output rate 86000 bits/sec, 50 packets/sec
!
Use this command to confirm that the interface
output rates match one G.711 stream,
which the
show interfaces fastethernet
output displays as
50 packets/sec and 80 kbps or more.
Step 3
show ephone summary
Example:
Router#
show ephone summary
!
File music-on-hold.au type AU
Media_Payload_G.711Ulaw64k 160 bytes
!
Use this command to verify that the Cisco IOS
software was able to read the MOH audio file
successfully.
