FAQ

VoIP Providers & SIP Trunk Questions

How does SIP trunking differ from traditional ISDN PRI lines?
ISDN PRI lines require expensive physical copper cables and rigid 30-channel increments. SIP trunking delivers voice over your existing internet connection with on-demand channel scaling and dramatically lower monthly fees.
How long does number portability take in Greece?
According to EETT regulations, number portability typically completes within 3 to 7 business days. The actual cutover happens within a pre-scheduled 15-minute window to guarantee zero disruption.
How much internet bandwidth does each VoIP call require?
Each concurrent VoIP call consumes approximately 80 to 100 Kbps using uncompressed HD audio codecs. A standard corporate broadband connection can effortlessly handle dozens of simultaneous calls.
