What do you mean with "ISDN numbers"?

Do you want a simple ISDN extension or a ISDN trunk (e.g. CO-trunk)?
If you want a ext., you have to know if you want a point-to-point or a point-to-multipoint (bus) configuration.

When I saw the title of this post I thought it referred to legacy AT&T ISDN multi-line phones, using 2B+D.
I'll still occasionally get a request to multipoint one with an existing phone on the LEN. Those require a SPID.

Siemens does have an ISDN station option or card? I wonder what kind of phone would be used?

STMD module was mainly used for ISDN trunks but can be configured for non-buspowered phones too. As there were not many pure isdn phones on the market, the subscriber option was used mostly for isdn videoconference systems or servers with isdn cards.
In fact this was long time before all of this functionalities were moved to ip/internet.
In central europe ISDN is dead, even co trunks are sip based nowadays - the STMD modules are kind of obsolete.

For example
ADD-SBCSU:11200,FBUS,DIR,1-21-2-0,SET600&DTE,3,3,2,2,1,1,0,0,N,0,0,,,SBDSS1,,SBDSS1,Y,Y,0,,,,,Y,N,N,,5,0,,;
ADD-SBCSU:11201,MSN,11200,,3,3,2,2,1,1,0,N,0,0,,,Y,N,N,5,,,,,,,,,,;

I wonder how many pars does this ISDN phone use? Looking t the line cord, appear to be more than one pair. The old AT&T ISDN sets used 3 pair,
the 3rd for power. I think the original Siemens 3000 (or Hipath) was designed to accept ISDN trunks by default - but as @RioGrande75 said about
ISDN service, the same is the case in the U.S.

Usually ISDN needs 2 pairs: ISDN

Yes - the AT&T 5ESS also had a 'U' option, 1 pair from the LEN, converted to 2 pairs on premise via an NT1 card.

Not sure what kind of presence Siemens PBXs (TDM or VoIP) have these days in the U.S. When I was with Siemens (formerly Rolm) they were based in Texas.
I heard tech support (TAC) is only from Germany now.
