XML push client/phone intiated?

[jolouis]

Aha I knew I'd seen it somewhere! Was looking for some info on something else and came across the answer to your question!

If you follow the link to the guide provided by the Yealink response, as promised you'll see on page 99+ on the PDF a full description (with example) of how to do PUSHXML using SIP Notify. That means you can send your XML through SIP, without requiring the IP and direct access to the phone itself. That will solve your problem!
