Sending * and # down ISDN line (United Kingdom)

I need to be able to send the sequence *21*0123456# and #21# down our ISDN line so that the line provider can enable and disable call features on demand. Is there a way to do this? It would be preferable to just dial the number from SwyxIT!

Hi Mahomed

On my ISDN-access (MSM) from Arcor, Germany I just have to dial 0*21*01234567# to send *21*01234567# via KEYPAD ISDN Messages to the central office. You can see it with the D-Channel Monitor:
