Global SIP
One enterprise voice strategy. Global PSTN reach.
HookZ VoiceEdge Global SIP simplifies how multinational organisations connect their communications platforms to voice services across countries. Instead of managing a fragmented estate of SIP providers, commercial agreements and integrations, enterprises gain a consistent service and operational layer for connecting Microsoft Teams, contact centres, UC platforms and enterprise telephony to PSTN services across supported markets.
THE GLOBAL VOICE REALITY
