call forwarding twilio

Hi! I'm working on a Twilio integration for handling phone calls and everything is working fine so far . I have a question about call forwarding (I haven't finished setting it up yet):

Let's say:

A person (P) calls my company's Twilio number (L1).

During the call, P asks to speak with a human agent.

I want to forward the call to a real employee (H1).

Question:
Can Twilio initiate an outbound call from L1 to H1 while it's still handling the inbound call from P?
In other words, is it possible for L1 to "bridge" or connect both calls (inbound + outbound) together?
Or do I need a second Twilio number/line to do the forwarding?

Thanks in advance!
