[Asterisk-Users] Snom 360, Hold Button & Asterisk v1.2

[Sascha]

We're running Asterisk at Home but upgraded to version 1.2 of Asterisk.  
After the upgrade the 'Hold' button on our Snom 360 phones now 
immediately hangs up a call instead of putting the call on hold.  Has 
anyone else had this problem and figured out how to fix it?

I ran 'sip debug' in the Asterisk CLI and it looks like when I hit the 
hold button it's sending a "Cancel" message if I understand correctly. 
Here is the output:
