Forwarding originating caller ID and Redirecting Number Information Element (RNIE)

[bradh8148]

I have a customer who would like to forward the originating caller ID when a call is forwarded back out of the PRI. The customer's Telco is requesting the RNIE (Redirecting Number Information Element) to allow us to pass Originating caller ID out of the PRI. We use an Adtran TA924e to connect to a Telco's PRI then the Adtran talks SIP to our PBX. I have already done some research on this and found another post mentioning RNIE  "Configuring SIP PRI to allow CallerID on Call Forward" Below is a copy of the example Config posted in that thread:

voice ani-list DIDs

  ani <inbound DID pattern 1>

  ani <inbound DID pattern 2>

!

voice trunk-list SIP_Trunks

  trunk T01

  trunk T02

!

voice trunk-list PBX_Trunks

  trunk T03

!

voice trunk T01 type sip

  sip-server primary <SIP server IP/Hostname>

!

voice trunk T02 type sip

  sip-server primary <SIP server IP/Hostname>

  match ani $ add diversion <Customer's main number>

!

voice trunk T03 type isdn

  <normal PRI config>

  caller-id-override number-inbound <Customer's main number> if-no-cpn

!

voice grouped-trunk SIP

  trunk T01

  accept $

  deny list SIP_Trunks

  permit list DIDs

!

voice grouped-trunk SIP_Diversion

  trunk T02

  accept $

  deny list DIDs

  permit list PBX_Trunks

!

voice grouped-trunk PRI

  trunk T03

  accept $

  permit list SIP_Trunks

I have some questions about the above config.

1. How many DIDs can be added to "voice ani-list DIDs".
2. The current config (Config before adding SIP_Diversion trunk) I am using for the customer in question looks a little different.
   1. In my Voice grouped-trunk SIP I am Permitting the voice trunk-list SIP_Trunks
   2. I also have  list fxs denied on the "voice grouped-trunk SIP"  This is used to prevent fax DIDs from being directed to the PBX instead of the FXS ports.  

Below is part of my config:

If I was to implement the SIP_Deversion trunk would I have to deny list SIP_Trunks on the voice grouped-trunk SIP?

Will there be any other issues with my config compaired to the example config?
