[Freeswitch-users] MWI not sent

[Peter Steinbach]

I have a Yealink T46G registered at our Freeswitch machine. MWI is
enabled on the Yealink Phone, I see a "message-summary" entry in
sip_subscriptions. So I think, presence is setup fine

Content of the sip_subscriptions table:
"proto" "sip_user" "sip_host" "sub_to_user" "sub_to_host"
"presence_hosts" "event" "contact" "call_id" "full_from" "full_via"
"expires" "user_agent" "accept" "profile_name" "hostname" "network_port"
"network_ip" "version" "orig_proto" "full_to" "id"
"sip" "200" "fs00.my.domain" "200" "fs00.my.domain" "" "message-summary"
"""Peter3 Buero"" <sip:200 at 192.168.1.72:5060>"

<sip:200 at fs00.my.domain:5060>;tag=1082071637" "SIP/2.0/UDP
192.168.1.72:5060;branch=z9hG4bK2245575863" "1513683832" "Yealink
SIP-T46G 28.80.0.130" "application/simple-message-summary " "internal"
"fs01.my.domain" "5060" "192.168.1.72" "-1" ""
"<sip:200 at fs00.my.domain:5060>;tag=WdayfEpssASN" "2821206"

Events are enabled on the freeswitch console
/events MESSAGE_QUERY MESSAGE_WAITING

When a voicemail is recorded, I see a number of recurring events on the
console (see below), but no NOTIFY message is sent to the phone.
However, after a while (after 10min or even after hours) the phone
receives its message.
When I delete all VM messages, the MWI is never sent to the phone,
although messages are prepared (MWI-Messages-Waiting: no), as I can see
them on the console.

If I set the parameter “send-message-query-on-register“ in internal
sofia profile, then MWI is updated with every register to the phone.
Alos on every restart of the phone. But as we cannot use short intervals
intervals due to some reason, this is not the solution.

Anybody has a hint, how to solve this?
