Are you talking about bbs (bulletin board system) phone numbers or isp (internet service provider) phone numbers? Can you be more specific?If you are talking about bbs phone numbers, OS/2 BBS still has a dial service as well as their web site ( http://www.os2bbs.com or http://www.os2.com [IIRC on the url]).
ISP's usually have phone numbers at their web site.
OS/2 Warp-ed to the very end.
