# Telephony

Telephony allows participants to dial into a video conference using a phone, providing an alternative way to join for those without web access. Once enabled, users can connect to your session using a standard phone number and PIN code.

### How to Enable Telephony?

1. To activate "Telephony", please reach out to our support team. This feature must be enabled on your pricing plan before it appears in the dashboard. 
2. Once "Telephony" is activated for your account, you’ll see a new option in the room settings called "Telephony". You can enable it per room where needed.
3. Configure dial-in details

   In the room settings, find the following fields:

   * **PSTN/SIP Number**\
     This is the phone number participants will call to join the meeting (e.g. `+1 234 567 890`).
   * **DTMF (PIN Code)**\
     Use this to insert the PIN used by the communication server.

     * If needed, add delays between digits using:
       * `W` for a 1-second pause
       * `w` for a 0.5-second pause
     * Stack delays if needed (e.g. `WW` = 2 seconds, `www` = 1.5 seconds).
     * For help setting up "Telephony", please contact our support team through [ticketing](https://www.digitalsamba.com/embedded-support).

   ### Joining a Meeting via Telephony

   Once Telephony is enabled for a room:

   * A new **"Telephony"** button will appear in the room for participants.
   * Clicking it opens a panel where participants can manage their phone connection to the meeting.
   * After selecting **Connect**, the system will show the status as **Connected**, and telephony users will be able to join the call.

   ### Managing Phone Participants

   * Participants who join via phone will appear in the participants list.
   * They will be clearly marked with a phone icon, their name (if provided), and the number they used to dial in.
   * Moderators can mute or unmute phone users directly from the participants list.

   * Only one bridge connection is supported per room at a time.
