I'm currently creating calls with a permanent squad with structured outputs attached to the permanent assistants in the squad via the vapi python server sdk (version 1.7.2). When I create calls with the code

async_vapi_client.calls.create(
        squad_id=`fc5b686e-4435-4628-9e6b-5ab71929b640`,
        phone_number_id="a08625a8-acf6-4832-b27c-8107ab28ebfd",
        customer=CreateCustomerDto(number=phone_number),
        assistant_overrides=AssistantOverrides(
            variable_values={"agent_name": agent_name, "candidate_name": candidate_name},
            max_duration_seconds=1800,
        ),
    )

the call still shuts down immediately at 600seconds, which is the default value of

max_duration_seconds

, even after I added the override of

max_duration_seconds=1800

in the

assistant_overrides

. I've tried to address this by setting

max_duration_seconds

on each assistant in the squad via the

assistant_overrides

field in each

SquadMemberDto

in the

await async_vapi_client.squads.create(...)

function call, to no avail. Is there another place that I should be setting this value, or an internal block preventing me from having longer calls? ID of an example of a call with this issue:

78098f9c-8ea7-4d87-ba1f-47d5b36b0e27

, which was created at

2025-09-25 16:46:02.746000+00:00

Note that the

ended_reason

is

exceeded-max-duration

even with the

max_duration_seconds

set to

1800

in the assistant overrides.

Thank you for the detailed context. To help pinpoint the issue: Are you using any organization-level or account-level settings in the Vapi dashboard that might enforce a maximum call duration (e.g., a global or telephony provider limit), regardless of the

max_duration_seconds

set in your code? This will help determine if the override is being superseded by a higher-level configuration.

Where would I find account level settings enforcing a maximum call duration?

You can find the account level settings for enforcing a maximum call duration in the account management section of your dashboard. Look for the settings related to call preferences or call limits, where you can set the maximum duration for calls.
