Configuring DSP Templates

The DSP Template determines the coders that can be used by the device and various
other functionalities. For a list of DSP templates and the maximum number of channels
supported by each coder, see 'DSP Templates' on page 839. You can select a single DSP
Template.
Notes:

To select a DSP Template(s):
1. To use a single DSP Template:
a. Open the General Settings page (Configuration tab > VoIP menu > Media >
General Media Settings).
Figure 13-13: Defining Single DSP Template in General Settings Page

number.
c. Click Submit.
d. Reset the device with a flash burn for the settings to take effect (see 'Saving
Configuration' on page 494).

DSP Channel Resources for Transcoding

In addition to DSP resources (channels) required for PRI trunk interfaces, the device
provides flexibility in making additional DSP resources available for IP-to-IP functionality.
This is achieved by the following:

Obtaining DSP resources from the Media Processing Module (MPM)

"Borrowing" DSP resources from the PRI interfaces (i.e., TRUNKS module)
DSP channels are required for the following:

IP-to-IP application: Each IP-to-IP call session includes two legs, requiring two DSP
resources.
Note:
Version 6.6
•
If no entries are defined, the device uses the default DSP template (i.e.,
Template 0).
•
A single DSP Template can also be configured using the ini file
parameter, DSPVersionTemplateNumber.
In some scenarios, the IP-to-IP application does not require DSP resources.
