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 Channel Capacity. You can select a single DSP Template.

If you do not configure a DSP template, the device uses the default DSP template (i.e., Template 0).

The following procedure describes how to configure a DSP template through the Web interface. You can also configure it through ini file [DSPVersionTemplateNumber] or CLI (configure voip > media settings > DSP-version-template-number).

To select a DSP Template:
1. Open the Media Settings page (Setup menu > Signaling & Media tab > Media folder > Media Settings).

2. In the 'DSP Version Template Number' field, enter the required DSP Template number.
3. Click Apply, and then restart the device with a save-to-flash for your settings to take effect.
