[Asterisk-Users] Call Transfer problems-am I missing something?

[alex at lava-net.com]

Hi All,

Recently got call-transfer somewhat working on my asterisk-1.0.9 
install, and came across an interesting problem.  I have an account on a 
VOIP Provider (voipbuster using iax to be exact) and use a line like 
this in extensions.conf to have it handle all outgoing calls beginning 
with 1:
exten => _1NNXXXXXXXX,1,Dial(voipbuster/00${EXTEN},t)
When I call someone and press # on the phone ( I've tried this with 
various softphones and a regular phone connected to a linksys pap2) 
Nothing happens.However, if the called party presses # they get the 
extension prompt, and can then transfer me to an other extension.  Does 
anyone know why the calling party can't initiate the transfer? am I 
missing something?
