For Lotus Notes Widget stuff...
1st, must be running Notes 8.
2nd, learn about widgets in Notes 8.
3rd, create a widget that opens *any* web page. Just get it configured.
4th, export the XML file from the newly created widget.
5th, modify the XML file to navigate to url="tel:<q>" (translated = tel:<q>).
6th, re-import the XML file back to widgets.
7th, add action to recognize the built in Phone Number (IBM put a lot of work iinto that recognizer).
8 - close all, open up any document, click on any under-line.
NOTE: I obviously gave a high-level overview here, there are some fine details in this that probably need to be addressed.
Now if someone can tell me how to auto-sync Lotus Notes address book with PCM contacts for free, I'd be very appreciative of it!
