Does anyone know if

transferCall

tool works when it's a web call? I'm testing the AI assistant using

Talk to Assistant

button in UI and I want to transfer the call to a phone number, but it seems not working properly.

The transferCall tool doesn’t fully work during web-based “Talk to Assistant” tests because WebRTC can’t transfer to phone numbers, so for proper testing, you need to use a real telephony..

I see, can I specify in the system prompt to ask the AI not to use transferCall tool if it's a web call?

Yes you can

I tried but it still runs the transferCall tool. here's part of my prompt: 8. Submit their question using

fwd_submitaquestion

. 9. Then, silently transfer them to a team member using

fwd_transfer

if this is a real telephone call from the user, do not transfer if it's a web call.

Pass callType as metadata and update the system prompt.
