[Asterisk-Users] MWI indicator on SNOM200 doesn't disappear

[Pertti Pikkarainen]

I have also complained about the change in MWI to SNOM.
My 2.03o phones still work with Asterisk but 2.04 versions do not.
However, you can turn off the MWI by pressing the MWI button but not 
remotely ( NOTIFY ).

I once got the example under from SNOM ( Asterisk version is under it ).

According to SNOM this is an example of the format the phone is expecting
in order to get MWI turned off.
The relevant difference really looks like to be the 'Message-Account'.

This is what Asterisk is sending at the moment.
And this is ok with 2.03o.
Does chan_sip2 send somehow different NOTIFY ?
