Intr-o perioada relativ scurta, telefonia pe Internet a evoluat rapid, numerosi producatori de software lansand-si propriile aplicatii de acest gen.Serverele de retea s-au perfectionat dotandu-se cu echipamente de procesare a vocii si actionand astfel ca o interfata intre reteaua de telefonie si Internet.A aparut posibilitatea de a comunica prin intermediul aparatelor telefonice clasice, dar pe reteaua Internet.
Solutiile privind tratarea diferentiata a serviciilor permit transmiterea cu prioritate a pachetelor de voce,ceea ce conduce la reducerea intarzierilor si pierderilor pachetelor de voce.
VOIP a devenit o solutie foarte atractiva pentru marile companii,care au gasit astfel posibilitatea de a reduce substantial costurile aferente comunicarii,folosind propria retea Intranet. Astfel, beneficiind de o banda mai larga decat in reteau publica, se obtine o calitate superioara a semnalului audio,iar cheltuielile se diminueaza considerabil,mai ales in cazul companiilor care desfasoara activitatea in mai multe tari, deseori situate pe continente diferite.
Pe langa Voice Over Internet Protocol,mai exista un serviciu numit Fax Over Internet Protocol (FoIP),prin intermediul caruia mesajele de tip fax pot fi expediate prin reteaua de date,prin extragerea imaginii mesajului fax dintr-un semnal analog si transformarea sa in date in format digital.
