asterisk users - Nov 2003 - iconnecthere incoming

Hi guys
I just registered an incoming number with iconnecthere and I'm trying to 
set up incoming calls from icconnecthere on my asterisk server.  I took a 
look at john todds sample sip.conf and extensions.conf file but for some 
reason my incoming is still not working.  At this point I wish to use 
iconnecthere merely for inbound calls.  Also my asterisk server is behind 
nat.  The following is my current sip.conf file or at least the part that 
I see as pertinent here.

[general]
register=15555555555:1111@sipauth.deltathree.com/15555555555
context = sip-incoming

The pertinent part of my current extensions.conf is this

[sip-incoming]
exten => _.,1,Goto(home,s,1)

Please note that 15555555555 above has been substituted for my 11 digit 
iconnecthere number and 1111 above has been substituted for my 
secret/password.  I have seen on the mailing list where nat = 1 seems to 
be used by some to get this working and I even saw this in john's sip.conf 
file; however it was not in the general section.  Can I place this in the 
general section?

Thanks a lot for any and all assistance.
AJ

I'm get the message waiting indicator on the Snom105 to show, however,
pressing the button only results in the phone trying to call the address
"asterisk" (I presume the "From:" in the trace below).

How can I specify this to be an extension e.g. 8500 such that when the user
presses the button, he enters the voicemail prompt? Perhaps even his own VM
menu...?

Regards
Thorsten Neumann
