A Dedicated Dial-In Number is a phone number tied directly to a user’s Personal Audio Conference. By using this number, the host, as well as participants, will not be prompted to enter a conference ID number when joining, however, it will still prompt for a host key if the host has not joined yet.

This phone number can only be used for Personal Audio Conferences, and are currently only US-based numbers.

Once uploaded when a participant dials into a personal audio conference using a dedicated dial-in number, they will receive the welcome message. The hold music will play while a participant is on hold. The audio files must be in the .wav format (8k, mono, ULAW or ALAW).

2. In the navigation panel, click Account Management then Account Settings.
3. Click the Audio Conferencing tab.
4. Under Telephone welcome message or Telephone on-hold music, click the Edit icon .
5. Browse for the desired .wav file and select it for uploading.
6. Once completed, repeat steps 4-5 for the other recording option, if desired. 
   Note: Once the file is uploaded, it will take 24 hours for the audio file to be used with the dedicated dial-in number.
