To help you set the maximum call duration in a Python agent for LiveKit, you can use the

max_call_duration

parameter found in SIP-related configurations. This parameter is available in the

CreateSIPParticipantRequest

and trunk configuration objects like

SIPInboundTrunkInfo

and

SIPOutboundTrunkInfo

within the LiveKit Python SDK. It’s important to specify it using the

google.protobuf.duration_pb2.Duration

type. Here’s a friendly example of how to set it in a `CreateSIPParticipantRequest`:

from livekit.protocol.sip import CreateSIPParticipantRequest
from google.protobuf.duration_pb2 import Duration

# Set maximum call duration to 45 minutes
max_duration = Duration()
max_duration.FromSeconds(2700)  # 45 * 60 seconds

# Create the request object
request = CreateSIPParticipantRequest(
    sip_trunk_id="trunk_123",
    sip_call_to="+1234567890",
    room_name="meeting_room",
    participant_identity="caller1",
    max_call_duration=max_duration  # Apply the duration limit
)

Similarly, you can easily configure an inbound trunk with a max duration like this:

from livekit.protocol.sip import SIPInboundTrunkInfo
from google.protobuf.duration_pb2 import Duration

max_duration = Duration()
max_duration.FromSeconds(3600)  # 1 hour

trunk_info = SIPInboundTrunkInfo(
    sip_trunk_id="inbound_trunk_001",
    numbers=["+1234567890"],
    max_call_duration=max_duration,
    # ... other fields
)
