Recently, we switched service providers on an existing TDE600.  After the fact, we found that the original service provider (CenturyLink) had made an exception to traditional PRI routing where the customer's main number (426-6000) was pointed to a third party head-end marketing service using a dedicated number 676-7669.  Callers would make their desired option from this head-end tracking service and then the caller would be transferred to the appropriate DID for the department at the car dealership they wanted.  <IMPORTANT>  Under this setup, the caller's number was carried through to the dealership when the call was answered.

Now, Spectrum (the new provider) refuses to peel off the main number (426-2000) and point it elsewhere.  Everything must be delivered over the single PRI and any routing must be handled on-premises.

Old scenario:  Call to 426-2000 > rings directly to 676-7669 and call processing is handled by third party > calls are delivered w/CID information as if directly-dialed.

New scenario:  Call to 426-2000 > rings directly to X222 which is permanently forwarded to 676-7669 > calls are delivered w/ dealership's main number as CID, not the caller's.
(Note:  This setup where the calls go to X222 first was something already set up in the TDE600 from years ago, which is why we didn't noticed the CID following issue until now).

Can anyone think of a manner in which calls to the main number can forward to the third party WITHOUT the CID information being stripped at the TDE prior to forwarding?  I've changed the ISDN options in system programming 2.9.17 CLIP to ISDN, but it had no effect.

NOTE:  If I call the third party's direct number (676-7669) directly and make my selection from their menu, my calling party ID information is displayed correctly, so we know that their end is working properly and the TDE is doing the blocking through the trunk/trunk conference created by the forwarding.

On the NEC you have to enable the station to pass along the caller ID.  It may be a class of service or extension option.

If Spectrum refuses to pass through the originating CID, you might want to consider porting the main number to a SIP provider that will.  Many of them still allow this.

Follow up:  Since Spectrum refused to do anything, the customer had us just build an auto attendant menu to answer these calls and everything works fine. 

For future reference, I've found from several other customer's systems, that when their PRI is on a 5ESS, this feature works fine.

Good to know, Ed.  Thanks.  :054:

We have a cable company here in our next of the woods Atlantic Broadband I had to fight tooth and nail with to get this to work.  I believe they use free switch in the back end but after getting to the correct person it was a 10 minute call and all was working!

I use to have to fight with Windstream on their DMS switches to get this working correctly. CO tech would always said they couldn't do it.  Then after taking no for an answer and escalating it would start working.

Never had trouble with Level 3 as they used 5ess in our area and when we needed it we would request and it would work.

We've had special dispensations for police departments after they signed documentation agreeing to accept the liability, but in general the carriers refuse.  They are all perfectly capable of allowing the originating CID to pass-through.  They simply refuse so they don't get embroiled in lawsuits regarding CID spoofing.
