Phone numbers including extenssions

Hi all, all the contacts from my Samsung Galaxy S5 were imported to the car's phone system. In my database I have a few contacts with their work phone numbers. Samsung uses a comma to differentiate the phone number from the extension. I noticed that this is not recognized by the Acura phone system. Acura uses the letter "P" instead of the comma. For this reason I can not call the already existing contact, I have to edit or change, don't know what to do. Anyone with any ideas? Acura team?
