Sinch Integration

Manage your telephony infrastructure and AI routing in one place. Import existing numbers from Twilio or Telnyx, provision new SIP numbers directly, or configure custom SIP trunks for any provider. Set up inbound/outbound routing, secure authentication, transport protocols, and assign AI agents to handle calls automatically. No vendor lock-in, no rip-and-replace.

Configure new extensions for your PBX system with SIP registration. Provide your PBX domain, SIP username & password, and set call directions. Advanced settings let you customize proxies, transport protocols, and system names. Whitelist our IP to ensure reliable SIP traffic and start automating calls with AI.

Transform your business phone system into a competitive advantage. Route calls professionally, eliminate voicemail waste, and ensure every customer interaction sounds like they're talking to a full enterprise team - even when it's just you answering from your home office.

Stop forcing customers to repeat themselves. VoiceInfra's Call Transfer lets your AI agent smoothly hand off live calls to human agents, team queues, or external numbers. Choose between fast cold transfers, reassuring warm transfers, or the new attended warm transfer — where the AI stays connected to both parties while briefing the human agent before stepping back. Map keypad digits for self-service routing and manage destinations with bulk CSV import. Seamless handoffs. Better customer experience.

Stop wasting time listening to automated phone menus. With IVR Detection enabled, your agent listens for keypad prompts and presses the right buttons automatically based on your instructions. It navigates complex menu structures on outbound calls to reach live agents or specific departments without manual dialing.
