Enable DTMF transfer on phone via asterisk

I need some help with a special VoIP Project.

The current state is pretty simple and straight forward.

Just a PBX with 4 extensions, and a trunk. All works well.

This is shown in the diagram as 'Before'.

One SIP phone however is very special.

It doesn't have a transfer button. So no call transfer can be initiated on the phone.

It should be possible however to initiate a transfer via DTMF tones.

The current PBX (main PBX) doesn't support tranfser via DTMF.

This is the tricky part: I *think* we need to put asterisk in between the main PBX and the phone.

I *think* Asterisk should be able to listen for DTMF tones and initiate a transfer to the main PBX if the correct DTMF sequence is entered on the phone.

I need someone who can tell me if this scenario will work, or suggest another solution.

Also i would like to hire this person to help me implement it.
