asterisk users - Nov 2006 - Cisco 7960 password/shared secret problem --- Related to OS X ?

Hello,

Whenever I put in a password/Shared Secret in my 7960 and try and get  
it to register with asterisk on OS X setup, the phone fails to register.

Oct 31 20:03:46 NOTICE[989]: chan_sip.c:11045  
handle_request_register: Registration from '<sip:575@10.10.10.46>'
failed for '67.121.71.120' - Wrong password

When I make the password blank in both sip.conf and SIPxxxxxxxx.cnf  
then it registers and works perfectly.  The same phone connects with  
a linux based Asterisk@home installation without any problems.

3 Questions:

1) How can I tell the actual password/shared secret the phone is  
transmitting to Asterisk.

2) Has anyone had any trouble configuring 7960s with passwords via  
the SIPxxxxxxxx.cnf file?

3) Do you think there is a bug in Asterisk that comes out when its  
compiled for PowerPC OS X  ?

Please let me know if you have any suggestions too.

Here is my setup:

I have a Cisco 7960s  running sip image : P003-08-4-00

I am setting the passwords via tftp server and the  
SIP<macaddress>.cnf file.
