[asterisk-users] Transfer to VoiceMail Asterisk 1.6

[motty.cruz]

Hello,
I'm using Asterisk 1.6 with Polycom SoundPoint 650, everything is running
fine except that I can't program a button on Polycom to transfer inbound
call to Voicemail directly. 

I have the following in my extension.conf 

exten => _547xx,1,Voicemail(${EXTEN:1}@default,u)

Reception can transfer directly to VoiceMail when dialing digit 5 I want to
make a softkey on Polycom 650 does anybody know how to accomplish tranfering
directly to VoiceMail? 

Thanks, 
Motty
