asterisk users - Mar 2005 - Call Transfers

I cant transfer calls. I try to hit # and then the extension and nothing 
happens. Any ideas?

Hi,

I have a setup where a GSM can be called from asterisk (via i4l ttyI*). 
Is there any possibilty for the person called this way to initiate a 
transfer to another asterisk extension ?

Thanks in advance
Bye,
