Voice Channels:
g711perdsp = 43, g726perdsp = 32, g729perdsp = 20, g729aperdsp = 32,
g723perdsp = 20, g728perdsp = 20, g723perdsp = 20, gsmperdsp = 32,
gsmefrperdsp = 20, gsmamrnbperdsp = 20,
ilbcperdsp = 20, modemrelayperdsp = 20
g72264Perdsp = 32, h324perdsp = 20,
m_f_thruperdsp = 43, faxrelayperdsp = 32,
maxchperdsp = 43, minchperdsp = 20,
srtp_maxchperdsp = 27, srtp_minchperdsp = 14, faxrelay_srtp_perdsp = 14,
g711_srtp_perdsp = 27, g729_srtp_perdsp = 14, g729a_srtp_perdsp = 24,
Step 6 show voice dsp group slot number
Use this command to display the current status or selective statistics of DSP voice channels for a specific
DSP group. For example:
Router# show voice dsp group slot 0
dsp 1:
State: UP, firmware: 8.4.0
Max signal/voice channel: 16/16
Max credits: 240
Group: FLEX_GROUP_VOICE, complexity: FLEX
Shared credits: 240, reserved credits: 0
Signaling channels allocated: 0
Voice channels allocated: 0
Credits used: 0
Oversubscription: can either be an indicator or a counter
DSP type: SP260x
Step 7 show voice dsp statistics device
Use this command to display DSP voice statistics for the device:
Router# show voice dsp statistics device
DEVICE DSP CURR AI/RST/WDT ACK MAC TX/RX PACK KEEPALIVE
ID ID STATE COUNT FAIL ADDRESS COUNT TX/RX/SKP

Step 8 show voice dsp statistics tx-rx
Use this command to display transmitted and received packet counts for the device:
Router# show voice dsp statistics tx-rx
Device and Port Statistics: PVDM-0
------------------------------------
8903 input packets at port, 15374 output packets at port
Device 0:
6853 packets from device, 11793 packets to device
0 Ctrl & 0 Media out of sequence packets, 0 packets drop
0 input error packets, 0 output error packets
0 resource errors packets, 0 gaints
vlan id: 2
