Federal law requires that electrical products used in the workplace be Listed (certified). Some states and cities required that cosummer products be Listed. UL is very conservative, similar to VDE, and will require that all components requiring certification display the UL mark. They do not accept other agency marks. There are other agencies, called NRTLs (National Recognized Test Laboratories), that can List your products. You may be able to find one that will be less stringent concerning the approval marks on components. TUV Rheinland is a NRTL, for example. Since they are very familiar with CENELEC component standards and marks, you may wish to consider them.
As you indicated, your devices must comply with FCC part 15. Class is acceptable for non-residential use, but Class B is required for residential use. If your device connects directly to the telephone network, you must also comply with FCC part 68's requirements for network protection, and you must also pass additional testing for the safety approval from the NRTL. Good luck.
