Can you tell me what kind of phone number in the UK begins with 0009? 
What might 000920125 be?

Hi pjdday,

UK calls beginning with "000" are international data calls. They are
used to improve the quality of facsimile and modem transmissions, and
especially for ISDN calls.

These numbers reach the same international number that would have been
reached by a voice call that has been dialled with the "00" prefix.

The two digits following the "000" are the International Direct
Dialing code for Pakistan (92).

I can't find any reference to "0125" as a national direct dialing area
code within Pakistan. Perhaps it might be a telecoms service that is
accessed by a short code.

I trust this helps to unravel the mystery.

"... it is necessary to use the special number prefix applicable to
data calls (000 instead of 00), which attracts a higher call rate in
recognition of the fact that the telco's normal speech-compression
techniques cannot be used on data calls."
