We are using Qsig IP trunks as tie/tandem between our S8720 servers. When a call is made that tandems across the IP trunk to the CM where our PRI's are connected for some reason when the call goes out the PRI the station ID is replaced with the BTN of the PRI. Does anyone know why this is happening? It only seems to happen to calls that go across the IP trunks. Any corrective steps for this? We have CPN activated on the station form and we also have send calling party number stroked on our PRI's.

I am at 3.1.2

You have to define the public unknown numbering scheme for the trunk group. I'd advise you of the command but you failed to follow forum guidelines and tell us what release you're running.

My apologies, our CM's are at release 3.1.2

change public-unknown-numbering x ... where x = your extension length. Fields are as follows:

Ext Len: Extension Length (i.e. 4)
Ext Code: A matching extension code. Similiar to ARS matching. i.e. 4 would match 4xxx, 43 would match 43xx, etc.
Trk Grp(s): Trunk Group. Blank = All trunk groups.
CPN Prefix: CPN Prefix: In the case of DID numbers here is where you would put the NPA-NXX ... i.e. 469698.
Total CPN Len: In North America this is usually 10.

So, if you have a total cpn len of 10 and an ext len of 4 with 469698 as the CPN prefix, then when extension 4000 makes a call the Caller ID is output as 4696984000 because the system appends the extension number onto the end of the CPN prefix for a total caller ID.

Now, in your case you probably only want the 4-digit extension number output. In that case, leave the CPN Prefix blank and make both the Total CPN Length and the Ext Len 4 and you should be good to go.

If you want the station name to go as well you must do 2 things:

1) In "change system-parameters features" set USNI Calling Name for Outgoing Calls to Yes
2) In the trunk-group set Send Calling Name to Yes.

We have the Public unknown table populated. The problem of the station ID being dropped and replaced with the BTN only occurs when the caller has to send his call across the IP trunks to get out the PRI. For users on the same switch where the PRI's live we don't have this problem. I believe there is something on the IP trunks that is stripping the CPN before it get's to the PRI. Is that possible?

OK. That's a horse of a different color. You must send the full CPN across the IP trunks in order to tandem it out the PRI. First thing to do is to look at the IP trunks (list trace tac) and make sure that the full CPN is coming across the IP trunk-group.
