a customer would like to associate to a speed dial button a prefix instead of a completed number. So, for example, pressing speed dial 1, there will be the prefix 00039222 on the screen of the phone. The phone should obviously wait for other digit to complete the number until the interdigit timeout expires. Does someone know if it is possible?
you can try to setup this button not as "Speed Dial" but as "Line". than you setup additional CSS for this line that point to special Route Pattern. and in this Route Pattern you can add prefix digits.
