### Answer
Based on the available sources, there isn't a documented way to have the agent actively "listen in" on a call after a transfer.
However, there are some related observations from community discussions:
Recording behavior after transfer:
Some users have reported that Retell continues recording calls after a transfer occurs. [(1) ](
) One user noted this behavior and asked if it was expected, to which a Retell team member confirmed "that's expected."
That said, this appears to be recording behavior rather than active agent listening/participation. Other community members have actually expressed interest in having this recording capability, while at least one user found it concerning from a privacy perspective.
Agent interruption issue:
There have been reports of the agent continuing to interrupt after transfers, which was identified as a Retell-side issue that was subsequently fixed. [(2) ](
) The workaround mentioned was to end the call yourself after the transfer with a timeout.
If you need the agent to remain involved in the conversation post-transfer, you may want to explore
warm transfer options which allow for three-way introductions before the agent disconnects. [(3) ](
)
