Problem with System Speed Dial

I used a CSV file to load my phone list to the system speed dial. If I creat a dial code of “99” for that phone entry, when I dial the speed dial command of “*0” + “99”, the system would say “The speed dial entry is empty.” I noticed that the system mistakenly thought I was asking to dial the entry “9” (there was no phone number stored under entry 9).

So, does this mean that system dial can only deal with single digit speed dial code? Or is the CSV uploading caused the system dial function problems?

System dial is an important function.
