[Asterisk-Users] SNOM Phones MWI, Hold & Retrieve buttons not working with Asterisk v1.2

[Sascha Deri]

We just upgraded to Asterisk 1.2 a few days ago. And now the Retrieve 
voicemail and hold buttons on our SNOM 360 phones are no longer 
working.  When you put a caller from one of our zaptel lines on hold it 
hangs up on them immediately. Interestingly, if you put an internal 
extension on hold it does not drop the call.

Additionally, the Retrieve voicemail butotn on the phones no longer 
work.  The MWI (Message Waiting Indicator) lights up, but when you press 
the button you get "Not Found sip:asterisk@" and busy signal.

Any ideas on what might be wrong on how to fix it?

Thanks!
