Hoping someone can help.

Each New Years I call my friend on the French side. This year when I telephoned (a landline)there was a recording stating all circuits were busy. I tried calling at other times and heard a busy signal and now I keep hearing a sound like a dead phone line. Is there a phone directory that someone may help me locate a new number for my friend or validate the old number. I did dial 011-590-590 plus the local number for 4 days with no success. Thanks for any help.
