Architect v2024.3.1 is running the show. Got this IVR flow handling inbound calls from the Ohio BYOC pool, and the Transfer block is doing jack all. Traffic hits the block, sends the INVITE to the trunk group, but the flow just sits there. SIP traces show the carrier sending the 200 OK, but Architect isn’t acknowledging it. Call drops after 12 seconds with a SIP 408 on the client side.
Checked the trunk config. Credentials are good. Registration is solid. Outbound routing works fine if the flow skips the IVR and just uses a direct queue. It’s only this specific block causing the hang.
Added a Wait block before the transfer. Didn’t help. Mic stays hot, customer hears music, then dead air.
The carrier support team is claiming they see the 200 OK leaving their side and no ACK coming back from the Genesys edge. Logs are clean on the trunk side, no re-registration events firing.
