Agent Can hear SIP Participant but cannot hear Browser Participant

[wansolution]

When a "SIP participant" called in to livekit, a room is created and the Agent with the name inbound-agent is dispatched to the room. The agent and "SIP participant" can hear each other.

Then i create a token for a "browser participant" to join the same room. once joined, the "browser participant" and the "sip participant" can hear each other. however the agent cannot hear the "browser participant". he can only hear the "sip participant".

is this a bug or a setting not done correctly?
