What Our Customers Build

Call manager

Perform phone calls between phones and apps, both mobile and web. Connect any phone number worldwide to meet your needs.

ACDs

Automatic Call Distributor queues and routes act as IP PBX for handling the inbound calls in a contact center according to rules traffic. The system tracks agents' statuses and forwards calls as soon as they are available.

IVRs

Build an automated telephony system that interacts with callers using DTMF or voice inputs.

Auto attendants

Create a voice menu that transfers callers to a specific agent or department without going through a telephone operator or receptionist.

Key Features

Phone numbers

Rent mobile, landline and toll-free phone numbers. Debug and create demo apps using test numbers.

Audio call recordings

Media files are stored in the Voximplant cloud for three months by default. If required, you can make a request and extend the storage time.

SIP trunking

A virtual alternative to a traditional phone line. SIP trunks carry signaling and media over IP networks.

SIP registration

Users register existing customer SIP phones or SIP endpoints with the Voximplant cloud.

Speech synthesis

Build IVRs and other apps with human-sounding voices. Voximplant supports 40 voice options provided by Google Speech Cloud, Amazon Polly, Speech Cloud, and Microsoft Azure TTS.

Speech recognition

Convert speech to text during a call or afterwards for further processing and analysis. We recognize 118 different languages and dialects supported by Google Speech Cloud, Microsoft Azure STT, Amazon Transcribe, and Yandex Speech Cloud.

Clear Audio Wherever Your Customers Are

Eliminate server latencies with P2P calling. The media goes directly from one VoIP phone to another instead of being routed through intermediate infrastructure.

Our data center network includes 14 POPs worldwide. This allows your customers to make and receive VoIP calls across 200 countries without noticeable loss of quality.

We use the Opus audio codec, which has a low algorithmic delay – 26.5 ms by default. Opus has the flexibility to reduce delay to as low as 5 ms by trading off quality or bitrate.

If you don’t have in-house developers or they are busy with other tasks, you can delegate VoIP app development to Voximplant experts. We’ll write custom code and build communications apps for your web or mobile service.

We’ll handle the entire development lifecycle – from creating an idea to VoIP app support and maintenance.
