Description:Here's an Endpoint:

{noformat}
[localnetwork]
type=transport
protocol=udp
bind=0.0.0.0:5060

[endpointtemplate](!)
callerid_privacy=allowed_not_screened
context=testing
disallow=all
allow=g722
dtmfmode=rfc4733
transport=localnetwork
direct_media=yes
send_pai=yes

[101](endpointtemplate)
type=endpoint
aors=101
auth=101
callerid="Malcolm Davenport" <101>

[101]
type=aor
max_contacts=10
remove_existing=yes
mailboxes=101@default

[101]
type=auth
auth_type=userpass
password=101
username=101
{noformat}

It starts up and it subscribes for MWI and it gets notice of it:
[debug1.txt|https://issues.asterisk.org/jira/secure/attachment/47618/debug1.txt]

If I then log in and check my voicemail, and delete the voicemail that's waiting, Asterisk never sends a NOTIFY to the endpoint (the phone) that there are no more waiting messages.
[debug2.txt|https://issues.asterisk.org/jira/secure/attachment/47619/debug2.txt]

It happens if I've got a message that I playback to remove, where the indicator should turn off due to NOTIFY, as well as if I leave a message that I expect to turn on the indicator due to NOTIFY.

I've reproduced this issue myself. Adding debugging messages, I can see that res_sip_mwi is subscribing to MWI stasis messages, and I can see that app_voicemail publishes an MWI event for the mailbox. However, I never see my stasis callback called in res_mwi_stasis. So something is happening in the stasis core that is resulting in res_sip_mwi never being told that mailbox state has changed.

I double-checked by switching from using res_sip and its ilk to using chan_sip, and I saw the same issue occur there as well. No NOTIFY was sent because the stasis callback was not called when the mailbox state changed.

Works for me.
