Enabling and configuring digit relay settings

Last Updated : Sep 18, 2019 |

About this task

Note:

Controlling applications typically override AAMS configuration using templates and template control modifiers. Digit relay configuration changes and preferences must be configured first on the controlling application and not on Avaya Aura® MS. See documentation for the controlling application to determine if any Avaya Aura® MS changes are required.

Avaya Aura® MS uses digit relay settings and the order of the enabled relay methods when negotiating digit relay with a client endpoint. These settings apply for inbound or outbound sessions.

Avaya Aura® MS also supports in-band DTMF. The system defaults to this option if no other option is configured or negotiated by Avaya Aura® MS. The preferred method of digit transmission is RFC 2833.

Perform the following procedure to enable and configure the digit relay support on Avaya Aura® MS.

Procedure

  1. Navigate to EM > System Configuration > Media Processing > Digit Relay (DTMF).




  2. On the Digit Relay (DTMF) page, select one or more methods from the Available list.
  3. Click Add to move the methods to the Enabled list.
  4. To change the priority rank of a method within the Enabled list, select a method and use the Up or Down buttons to move it within the list.
  5. Choose the required payload type option:

    • If a dynamic payload type is required, select Assign RFC 2833 Format Type Dynamically.

    • If a fixed payload type is required, select Specify Type. In the Specify Type field, enter the value to use in the payload type field of the RTP header when transmitting RFC2833 encoded digits.

  6. Click Save.
