asterisk users - Jan 2017 - How to send SIP_NOTIFY messages with variable content ?

Hello,

One common mean to remotely configure a phone is to send it some XML data
using HTTP.
Of course, this XML data is vendor specific but thanks to Asterisk multiple
tools, it is quite easy to customize your dialplan to both build and send
this specific XML data.

I have just discovered one interesting capability from one phone vendor:
getting XML data from incoming SIP NOTIFY messages instead of plain HTTP.

This has an advantage with remote phones as you do not have to keep an HTTP
connection alive to Asterisk box send XML content to registered phones.

I have just tried this capability: it works fine but I am now facing an
issue: for the moment, I must regenerate and reload a specific sip_notify
config file, each time I need to send some specific content.

If I am not mistaken, there is no Dialplan function or application able to
send SIP NOTIFY, right ?

Would you rate it as a welcome addition, either for SIP or PJSIP stack ?

Regards

Thinking over my previous, I wonder if sipsak could be used to send
outgoing SIP NOTIFY messages.
Would both Asterisk and sipsak be able to share networks resources ?

Thoughts ?

I would be very interested in using sipsak for something like this.  What 
have you tried so far?

One can send a SIP notify with a check-config to the phone and have the 
phone re-download it's configuration files from a provisioning server.

In the CLI, you can do a SIP NOTIFY with one of

     cisco-check-cfg, grandstream-check-cfg,  polycom-check-cfg, 
sipura-check-cfg, snom-check-cfg

and the extension.

I've done it with Yealink phones too, don't have the proper syntax in 
front of me though.
