asterisk users - Oct 2004 - Need help with RDNIS on ISDN PRI

Still looking for some feedback...

We are trying to configure our * box to receive RDNIS using ISDN PRI
circuits from a Lucent 5ESS so that when a call gets forwarded to the vmail
system (using call forward no answer) we get the original dialed digits to
identify the mailbox owner.

The local telco is now saying that Lucent is telling them that this
feature is not available on the 5ESS switch but he is not sure if Lucent
is giving them the "brush off or not".

Is anyone getting RDNIS on a Lucent 5ESS over ISDN PRI? If so could you
provide me the telco contact so that I can have my telco guy call them to
see how they set it up?

Alternatively, is anyone using ISDN PRI and RDNIS to identify the mailbox
owner? If so, what is the upstream switch and was there a special feature
you needed to have provisioned on the PRI to get the RDNIS?

Thanks,

Mike
