I have a bunch of left over modular jacks from work and would like to use them at home but the problem is, at home we didn't use CAT5, we used standard phone cable.

Take your pick buy phone jacks or make custom phone cables. RJ-11/12 does not fit into RJ-45.

Actually, wizard-fred, you have that backwards. An RJ-45 plug will not fit into an RJ-11 outlet. An RJ-11 will fit into an RJ-45 outlet.
So, if you want to use RJ-45 plugs, you would have to have RJ-45 outlets in your walls. If you don't have RJ-45 outlets in your walls, you'll have to use RJ-11's

RJ-11/12 plugs fit into RJ-45 jacks but not correctly. Sometimes their removal requires a lot of effort. The phones use the two middle connection 3 & 4 for line 1, 2 & 5 for line 2
