On the 8830 I could enter a calendar entry with a <phone number> <space> x<extension> and then the phone would dial the number with a pause where the x is. The x pauses for 3 seconds. For example:
1-555-555-1212 x234
I could cut that from the calender and paste to the dialer...very convenient for conference calls.
That doesn't seem to work on the storm. the cut and paste loses the "x"
I tried "p" but that didn't work.
