Regarding your question about SIP trunk changes (for example disabling KRISP): the change takes effect immediately once the trunk update is processed. You can test right away — just note that only new calls use the updated setting; any calls already in progress will keep the configuration that was active when they started.
If you want, I can point you to the API calls to verify the trunk setting (
GetSIPInboundTrunk
/
ListSIPInboundTrunk
) or walk you through making the update.
