Is it possible to configure a specific timeout threshold for outbound calls initiated through the Make Call block in Genesys Cloud Architect when targeting a BYOC trunk?
We are managing 15 BYOC trunks across the ap-southeast-1 region. Recently, we encountered a scenario where a carrier-specific failover logic triggered a secondary trunk that has a slightly higher latency due to peering issues. The Architect flow proceeds to the Make Call block, but instead of waiting for the SIP 200 OK or a proper 480 Temporarily Unavailable, the platform returns a 408 Request Timeout error after exactly 3.5 seconds.
The carrier logs show the INVITE was received and processed, but the response simply arrived too late for the default platform timeout. We need to extend this window to approximately 8 seconds to accommodate the carrier’s negotiation time without impacting our primary low-latency trunks.
Checking the API documentation for POST /api/v2/architect/flows, there does not appear to be a direct parameter to override the SIP timeout for specific outbound routing objects. Has anyone successfully adjusted this behavior via the SIP URI destination settings or through a custom data attribute passed to the trunk group? We are currently seeing a 12% drop in connect rate on these specific failover paths.
