The IP Telephony solution covers the design, structuring and implementation of voice communication systems based on the IP protocol, integrated with the corporate network infrastructure and oriented toward service convergence.

The architecture is designed to ensure voice quality (QoS), availability, scalability and interoperability with legacy systems or unified communications platforms, enabling centralized management, mobility and integration with business applications.

A3A Engenharia de Sistemas develops each solution based on defined functional requirements, traffic analysis, capacity sizing and prioritization policies, ensuring operational stability and alignment with best practices for converged network engineering.

Scope of Work

Architecture and Planning

  • Survey of communication requirements and extension sizing
  • Definition of the Voice over IP (VoIP) architecture
  • Bandwidth capacity planning and traffic prioritization (QoS)
  • Voice VLAN design and logical segmentation
  • Sizing of communication servers and gateways
  • Definition of redundancy and high-availability policies

Deployment and Integration
