[Alteration of hallo, alteration of obsolete holla, stop!, perhaps from Old French hola : ho, ho! + la, there (from Latin illāc, that way).]

from Wiktionary, Creative Commons Attribution/Share-Alike License

Hello (first attested in 1846) from hallo (attested 1840), from holla, hollo (attested 1588). This variant of hallo is often credited to Thomas Edison as a coinage for telephone use, but its appearance in print predates the invention of the telephone by several decades.
