Hi, We are facing an issue with the Call Transfer feature. Phone Number: +16\*\*\*\*\*\*\*\*\* Phone Number Type: retell-twilio When our AI agent tries to transfer a live call to an Indian number (+91), it fails with: “Transfer call cannot be completed, probably don’t have the permission to perform the transfer.” Steps already taken: - Updated allowed\_outbound\_country\_list via PATCH API to include “IN” - Verified via GET API — list correctly shows [“US”, “CA”, “IN”] - Transfer is still failing during live calls Since the number type is retell-twilio, we believe the Twilio SIP trunk managed by Retell is blocking transfers to India. Please enable India (+91) outbound call transfers on the Twilio trunk for our number +16\*\*\*\*\*\*\*\*\*. Thank you. ---

Hello @shyam The issue here is that you are transferring an Indian number to another Indian number, which Twilio does not allow. Please turn off the show the display number as the user’s number, which will fix this . Thank You ---

Hi, Thank you for the quick fix — the call transfer is now working perfectly! One more question — after the transfer connects the customer to the collector, can the conversation between the customer and the collector also be recorded? We would like to have the full call recording, including the transferred leg. Is this something that can be enabled on our account/Twilio trunk? Looking forward to your response. Best regards, Shyam ---

You can still record the call on Twilio until RetellAI doesn’t have that feature.
