Technical support from real SIP/VoIP engineers
Colombia is ideal for nearshore call centers due to its time zone alignment with the US East Coast (UTC-5, same as EST), a rapidly growing bilingual workforce fluent in English and Spanish, cultural proximity to the US, and the lowest SIP latency of any offshore BPO market at just 40-80ms round-trip. Major BPO hubs in Bogota, Medellin, Barranquilla, and Cali offer a deep talent pool at competitive costs.
SIP call latency from Colombia to the US is typically 40-80ms round-trip, the lowest of any offshore BPO market. This is possible because of Colombia's geographic proximity and direct network paths through IPComms' Miami and Dallas Points of Presence. This ultra-low latency allows the use of G.711 (ulaw) codec for full-quality audio, making calls indistinguishable from domestic US calls.
