In attending/hosting conference calls, I'd like to be able to dial the conference call provider and enter the required PIN code directly from the entry in my calendar.

The process I currently use is:

1. When scheduling the call - create the calendar entry for the call, including in the field [Where - Event Location] the number and PIN to dial in the format `+CCAAANNNNNNN,,PPPPPP#,` where CC = country code, AAA = area code, NNNNNNN is the conference call telephone number, PPPPPP = the PIN code needed. The first two commas are to wait long enough, the third comma is to stop the # required to enter the PIN from not being recognised.
2. When setting up or dialling into the call: 1. Open the calendar entry, 2. **Edit**, 3. Select the text in the "Where- event location" field, 4. **Copy**, 5. Switch to the dialler, 6. **Paste**, and then 7. **Dial**.

Whilst this works, is is clearly not as efficient as clicking a link in the Calendar Event `+CCAAANNNNNNN,,PPPPPP#,`. Frustratingly, this even comes up as a hyperlink, but Android gives me the options Earth & Maps (as well as two other proprietary links - Radar which is part of the App "GPS Status", and ZVVFahrplan - part of the Zürich city public transports system's app).

I have tried all permutations that I can think of [rfc3966.txt](http://www.rfc-editor.org/rfc/rfc3966.txt): The tel URI for Telephone Numbers. For example
`tel:+442012345555,,123456#,` or, `tel:+442012345555","","123456"#"","` or `tel:+442012345555PP123456FP`

If if put the number in the Notes field within the Calendar event, it turns into a diallable link, but chopped up. I can dial the number, but not the PIN.

Any thoughts or ideas?
