Answer 2

North American area code +1 456 is used for 56Kbps ISDN data connections from other countries into the United States. If an international caller places an ISDN call to an ordinary number in the U.S., there is no guarantee that the circuit will be any better than voice-grade. Using a 456 number guarantees a 56K data-grade connection. The party on the U.S. end of the call needs to pre-arrange the 456 number with their telephone provider.

International country code +45 is Denmark.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
