The client may connect to Avaya Aura® MS through a PSTN or other form of internet gateway device. In this case you must configure the gateway device to properly translate digits in a format that negotiates with Avaya Aura® MS. The following are the supported digit signaling formats:

To communicate digits, the client and the gateway device must use the same digit signaling formats.

Some gateways that translate in-band digits into events, such as telephone-event or INFO digits, fail to completely clamp the received tones. These tones are heard by Avaya Aura® MS and can trigger unexpected behavior.

If necessary, collect SIP messaging to resolve the nature of digit communication issue between the client, gateway, and Avaya Aura® MS.

In some cases, such as conferencing, clients unintentionally send digits into the conference through their microphone. The system detects these digits as conference controls in the conference. For example, a person near a conference user dials a number on a speakerphone. The digits can carry in the conference over the microphone of the active user.

When users report digit collection issues, ask about the client type and surroundings to identify the cause of any unexpected conference behaviors.
