Poland SIP Trunking FAQ

Poland is a leading European call center hub due to its highly educated workforce with many university graduates, strong language skills (Polish, English, German, French, and more European languages), EU membership providing regulatory advantages, competitive operational costs compared to Western Europe, and major BPO hubs in Warsaw, Krakow, Wroclaw, Lodz, and Katowice with strong IT and technology sectors.

Polish call centers are highly multilingual, supporting Polish (native), English (widely spoken and taught), German (especially common due to proximity), French, Spanish, Italian, and other European languages. This makes Poland ideal for serving pan-European markets as well as US customers. Many Polish agents have near-native or fluent English proficiency.

Typical round-trip latency from Poland to the US is 120-160ms, which is significantly lower than many other offshore BPO locations due to Poland's geographic proximity to transatlantic cable routes. Major Polish BPO hubs like Warsaw, Krakow, and Wroclaw have excellent fiber infrastructure connecting to European internet exchange points with direct transatlantic connectivity.
