Well.. Now I'm confused.

Recap.. Couldn't appear to get out going callerid to work on a UK NTL
PRI connection.

Id been testing it with my Orange Mobile phone.. Dial the 07973xxxxxx
and it displays private.

Called my girlfriend tonight on our land line (all be it NTL again but
this time analogue), got her to do 1471 and feck me, it read back the
callerid Id been putting through.

Only been able to try it on Orange and NTL residential at the moment.

Ill try it to a BT line tomorrow morning.

I'm really stumped now..

Why does it work on one and not on the other?

This happened to me here in the US. T-Mobile was the carrier that I had
a hard time with, land lines, and all other carriers worked fine. It
seams that T-Mobile, was not accepting calls that it could not confirm
the ANI on.

The solution was on the Telco side. I had enabled a feature that allowed
me to change the ANI of outgoing calls to those within my DID block. Any
calls outside that block the telco would send out with a ANI flag of
'presented, but not-confirmed' message.

Try setting your CallerID to your BTN (Billing Telephone number, or ANI)
and see what happens.

Hope this helps, don't know much about the UK NTL lines but this had me
stumped for a while......

I've had the same issues with T-Mobile. Thanks for pointing out the
exact cause. I did speak to someone in their back-end offices and they
did resolve it for a short time, then it reverted back for a bit and
started working again. Now it seems to work 90% of the time.
