It is certainly possible that BT could do this, but I very much doubt that
they would go to so much trouble for so little gain. BT and Telewest
interconnect with each other using SS7 which as far as I know is done over
n x 64kbps channels (which are delivered over E1/E3 spans). So
theoretically there is no reason why your BT customers shouldn't have as a
good a time as your Telewest customers.
Have you tried this yourself from a BT line?
When did the problem start happening (or has it always been like this)?
Do you have any NTS (Number Translation Services) such as an 0845 number?
Does it still happen if you dial the geographical number directly?
Are all the BT customers that you have shown below geographically close to
each other (i.e. on the same BT exchange)? Are they out of the city or in
the centre of town?
>From the data you have given below, it does look like you are being muxed
somewhere, but I very much doubt it's on the Telewest/BT interconnect.
P.S. We also have our PRI through Telewest.
