asterisk users - Jan 2007 - Problems with park

Hi.  I've spent the past four hours on this... if it's a FAQ, I
apologize.

I am setting up a system with Asterisk 1.4, a TDM400 (3 FXO, 1 FXS) and 
3 Aastra 480i CT phones.  (1.4.1 firmware.)  I have the system mostly 
working, but am still having trouble with a couple features.  This email 
will deal with parking.

First, I think I should point out that transferring calls seems to work 
fine.  If I call into an FXO and have it ring on extension 102, I can 
answer the call and transfer it to extension 101.  (Both Aastra 480i CTs)

I have followed the (very brief) instructions on voip-info.org titled 
Asterisk Call parking.  Basically, I confirmed that features.conf was 
already set up properly, and made sure parkedcalls was included in my 
local context.  If I dial in via the FXO and answer the call on x102, 
then hit transfer 700, I hear the announcement "701".  When I hang up 
the phone, the LCD displays "Transfer Failed" and I get a bunch of 
orphaned channels.

I have made sure that all my Dial commands end with ",tT" and have
also
added "canreinvite=no" to my sip.conf. 

Am I missing something simple? (probably)  Can someone please point me 
in the right direction or let me know what config files you need to see?

Thanks in advance.

Oh, I just noticed, transferring _doesn't_ work fine... If I call from 
x101 to x102, and try to transfer the call to an extension set up with 
the Music on hold application, I get the same "Transfer Failed" 
message.  Same thing if I call in via the FXO.  Now I'm even more lost, 
but perhaps the problem isn't my parking config.

Are you doing a blind transfer or attended transfer? I'm assuming you're
using the phone's transfer button. You may need to press transfer a 
second time to complete the transfer.
