For regarde-les I think I hear a liaison which sounds, to an English person something like regar-delay. 

Similarly for verse-les I think I hear a liaison which sounds like ver-selay.

However I don't hear a similar liaison for téléphone-lui or appelle-les.

Is there a rule for when to  liase the final part of a word ending in the letter e?

Can one not say "la semaine passee", to mean the same thing as "la semaine derniere"? (I can't find accents)
