Transfer calls to any extension?

Hi to all.

I need to transfer call to any extension in a dialplan context:

; Transfer calls intended for Extension 123 to Extension 130:
exten => 123,1,Transfer(130)

I need to allow agents to transfer to any extension:

; Transfer calls intended for Extension 123 to Extension 130:
exten => 123,1,Transfer(extension entered by agents on the phone)

Thanks in advance!!!

i found it, Just adding tT in Dial(sip/${exten})
extent => _2XXX,1,Dial(sip/${EXTEN},tT)
