Ok, let's see if we can solve the mystery..

pjsip.conf

[endpt-home](!)
type=endpoint
disallow=all
allow=g722
allow=alaw
allow=gsm
ice_support=yes
context=from-home
allow_subscribe=yes
mwi_subscribe_replaces_unsolicited=yes

[11](endpt-home)
auth=11
aors=11
callerid=*scrubbed*
mailboxes=11
voicemail_extension=411

extensions.conf

[from-home]
exten => 11,hint,PJSIP/11

include=>local-extens
include=>trunk-out

This is the exact subscribe message and reply as recored by the Snom M9 Logging facility.

I did also try all those variants:

exten => 11,hint,PJSIP/11 at woody.ch
exten => 11,hint,PJSIP/sip:11 at woody.ch
exten => 11,hint,PJSIP/sip:11
exten => 11 at woody.ch,hint,PJSIP/11

Any 'hint' welcome on why MWI subscription just does not work on those SNOM M9 phones.
