Warm Transfer Bridged Error
# ❓・bug-report
v
Hi Support Team, I encountered a critical failure in the Agentic Warm Transfer workflow where the bridge_transfer tool reported a successful connection, but the actual SIP bridge never occurred. The Incident: Interaction: The Transfer Agent successfully spoke to the human representative. Acceptance: The human rep agreed to take the call. Tool Execution: The agent executed bridge_transfer. Log Result: The logs show the tool successfully returned: Tool Result: {"status": "bridged"} Actual Behavior: despite the "bridged" status, the audio was never connected to the human representative. The user remained on the line with the Transfer Agent (in a dead/silent state) until the system timed out and terminated the call. The Logs: Call ID: call_3868ad6fdde4b184836fe847 Agent ID: agent_4b155057108f3b0e0c9d769eef Tool Call ID: 36de04d5e6937064 (from my logs) My Request: Why is the API returning {"status": "bridged"} before the SIP media stream is actually established? This "false positive" is breaking our logic because our system marks these calls as successful "Warm Transfers" even though the customer was never connected. Can you investigate why the bridge signal fired but the media failed to traverse? Thanks

Yes, have you tried increasing the agent detection timeout?
v

Hello @Vako-SV , the issue could be from our side , I've let the team know I will update you soon , If you can try the conversation flow for this feature it should be working fine.
v
i cant change the whole agents now into conversational flow sir - i use 4 agent combination for 1 purpose and only 1 transfer agent - i tried to work with Single prompt agent and tranfer agent to be conversation flow - but its not working
how ever it works when i reject the call for cancelation its working
its not working when it has to connect user with human rep
o
got it, I've report it to the team,I will get back to you on this.
