UPDATE - Verify the Number you're calling from...

Phoneman2 wrote an awesome FAQ back in 2003 that showed people how to write a vector so the system will speak back to you with the extension you're calling from (great for analog ports, and older digital phones that didn't natively display your number on the screen):
http://tek-tips.com/faqs.cfm?fid=4624

As the system's feature set has expanded, people may work in a blended environment (4-, 5-, or 7- digit extensions), and with newer software vectors have now become 99 steps. So, I enhanced this a bit, and gave it a tad more logic to identify a blended extension environment (its built to handle up to 10 digits, so could work for external calls as well). Here you go, enjoy. In the below examples, the last digit of each announcement number IS the spoken digit.

I tried like mad to see if I could use a system-wide variable to jump positions in the ANI and Announcement Filename, which would have reduced this to 1 vector and make it handle unlimited length ANI (using a cyclic counter to step), but darn if I ultimately couldn't get the system to change positions easily. If any of you know sys variables well enough, that would make this just uber-awesome.
