asterisk users - Feb 2005 - IAX native transfers

I am having problems getting any form of call transfer working.
I have reconfigured blind transfers to be #1 and assisted transfers to
be *2 but these are not working.
Looking at the wiki
(http://www.voip-info.org/wiki-Asterisk+cmd+Transfer) it it does not
mention IAX so I assume I have to use the native IAX transfer supported
by Diax?

I have tried using Diax but am getting a problem that after trying to
transfer both ends of the line hang up. Here is the asterisk log:-

DIAX supports only unattended transfer using '#' key (common way) or
using the Transfer Button.
Have you tried both of them?

Best regards,

No idea.  IAX does not support inband DTMF, so that is not your 
problem.  (inband DTMF only works with ulaw and alaw codec -- this is 
not specific to Asterisk)
