Cisco VGD 1T3 Voice Gateway Software Configuration Guide
DETAILED STEPS
Command or Action Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
dial-peer voice tag { pots | mmoip | voip }
Example:
Router(config)# dial-peer voice 10 voip
Defines a particular dial peer, specifies the method of voice
encapsulation, and enters dial-peer configuration mode:
• tag—Digits that define a particular dial peer. Range is
from 1 to 2147483647.
•
pots—Indicates that this is a POTS peer that uses VoIP
encapsulation on the IP backbone.
• mmoip—Indicates that this is a POTS peer that uses
MMoIP encapsulation on the IP backbone.
•
voip—Indicates that this is a VoIP peer that uses voice
encapsulation on the POTS network.
Step 4
codec gsmamr-nb [ packetization-period 20 ][ encap
rfc3267 ] [ frame-format { bandwidth-efficient |
octet-aligned [ crc | no-crc ]}] [ modes
modes-value ]
Example:
Router(config-dial-peer)# codec gsmamr-nb
packetization-period 20 encap rfc3267
frame-format octet-aligned crc
Specifies the GSMAMR-NB codec for a dial peer:
• packetization-period 20—Sets the packetization
period to 20 ms.
• encap rfc3267—Sets the encapsulation value to
comply with RFC 3267.
•
frame-format—Specifies a frame format. Supported
values are octet-aligned and bandwidth-efficient. The
default is octet-aligned.
• crc | no-crc—CRC is applicable only for octet-aligned
frame format. If you enter bandwidth-efficient frame
format, the crc | no-crc options will not be available
because they are inapplicable.
•
modes—Valid values are from 0 to 7. You can specify
modes as a range (for example, 0-2), or individual
modes separated by commas (for example, 2,4,6), or a
combination of the two (for example, 0-2,4,6-7).
Applicable only to GSMAMR-NB codec support.
Step 5
rtp payload-type cisco-codec-gsmamrnb number
Example:
Router(config-dial-peer)# rtp payload-type
cisco-codec-gsmamrnb 110
Configures a dynamic payload-type value for the
GSMAMR-NB codec.
• The default value is 117.
•
There are other options available with this command,
but an abbreviated syntax is shown here to clearly
indicate the keywords and options for the
GSMAMR-NB codec.
