apps/mwi: why notify and some errors in created request

[dunst0]

Why was the method changed from PUBLISH to NOTIFY? apps/mwi/mwi.cpp#L109-L116

This module pre sets a Route-Header to the presence_server, which leads to the following SIP request:

NOTIFY sip:x.x.x.x SIP/2.0
Via: SIP/2.0/UDP x.x.x.y;branch=z9hG4bKbQU7laXT;rport
From: <sip:[email protected]>;tag=177BE301-58D2463A00053860-1F4F4700
To: domain.de
CSeq: 10 NOTIFY
Call-ID: [email protected]
Max-Forwards: 70
Event: message-summary
Subscription-State: active
Content-Type: application/simple-message-summary
Route: <sip:[email protected]>
Contact: <sip:x.x.x.y:5060;transport=udp>
Content-Length: 105

Messages-Waiting: yes
Message-Account: sip:[email protected]
Voice-Message: 1/0 (1/0)

I would like to use the module but not as it is, because it doesn't work for me. Are there any problems regarding a change back to PUBLISH method or should it be configurable? The To header will be bad sip, so I will fix it and I will remove the preset route set and let it be set in the config, because I don't need it.
