Phone numbers with extensions

Has anyone found a way to enter a phone number and a related extension into the Prius phone book or just dial an extension after initiating a call? My wife's pager and voice mail system requires that an additional 5 digit number be entered after the initial number is answered. I haven't been able to find a way to store and use the extensions of her important co-workers so she can call them from CarMyne. I have also tried to manually dial the extension by hitting the 0-9 button that displays after the main number is connected. This displays a numeric key pad and I can punch in the extension but it doesn't seem to get transmitted to pager system. We have a Treo 650 which may be part of the problem since it does not handle phone extensions well either.

 

Thanks for the reply. Actually dialing while moving is not as important as being able to store and use an individual's extension. After trying several more times, I was able to manually enter an extension while the call was in progress by using the 0-9 button. However, there doesn't seem to be a way to store usable extra digits for an extension with the phone number or to access a memory location for the extension during a call. Just hoping someone may have discovered a usable work around for long phone numbers.

 

I found this information in the Nav manual that seems to show how phone extensions can be used. It refers to a continuous tone signal (I'm not sure what that is) and the marked sign:

"The continuous tone signal is the marked sign
(p or w) and the number following telephone
number. (ex. 056133p0123w#1)"

However, if I put a p or w into a phone number, it won't transfer to the phonebook. Has anyone tried to use phone extensions in the Prius?

 

I still haven't found a solution for long phone numbers. So, I'm bumping this up to see if anyone else has.....
