• Enhanced productivity with unified communications across offices and remote teams
• Seamless integration with CRM, ERP, and contact-center software

Cyvotel approaches network design with a single priority: keeping your voice and data services available, performant, and secure. Our deployments are optimized for VoIP-first operations — with topology decisions, monitoring, and routing engineered around the realities of real-time voice traffic.

Network & Voice Redundancy Highlights:

• Dual-core network topology with redundant distribution and active-standby or active-active routing to eliminate single points of failure.
• Dual-ISP connectivity and automatic failover (BGP / dynamic routed failover) so internet and SIP trunk reachability is maintained even when a primary provider has an outage.
• Redundant SIP trunking from multiple carriers and carrier diversity to ensure voice call continuity and route optimization.
• Session Border Controllers (SBCs) deployed in HA pairs for secure, scalable SIP edge protection and SIP normalization across providers.
• Geo-redundant PBX clusters (active-active or active-standby) that replicate call state and voicemail so calls are preserved during a site failover.
• VLAN/QoS design to prioritize voice traffic across the network and avoid jitter, packet loss, and latency spikes on converged links.
• Local survivability and branch fallback so remote sites maintain local calling and emergency dialing when central links are interrupted.
• Proactive monitoring & call-quality telemetry (RTCP, MOS, NetFlow) integrated into NOC dashboards for immediate detection and fast remediation of voice degradations.

Automatic Failover Architecture:

• <50ms failover detection and switching
• Zero dropped calls during ISP transitions
• Automatic route optimization based on real-time quality metrics
• Multi-WAN load balancing for optimal bandwidth utilization

Our network designs form the backbone of every modern communication ecosystem. With Cisco-certified engineers and deep VoIP experience, Cyvotel builds networks that intelligently manage traffic, prioritize real-time voice, and recover automatically from link or hardware failures.

Core Design Principles:

• Redundant core and distribution layers using Cisco Catalyst or Nexus platforms to maintain continuous connectivity even during equipment or link failure.
• Multi-path routing with BGP and OSPF for automatic failover, load balancing, and dynamic path optimization across WAN and Internet links.
• Dual ISP connectivity for voice and data, ensuring uninterrupted SIP trunk access and VPN availability through intelligent route failover.
• Layer 2 and Layer 3 segmentation for isolating voice, video, and data traffic — maximizing performance, reducing latency, and strengthening security.
• End-to-end QoS (Quality of Service) policies that prioritize voice packets across LAN and WAN interfaces, minimizing jitter and delay.
• Redundant power and switch stacking configurations for zero-downtime switch upgrades and continuous forwarding during hardware maintenance.

VoIP Network Optimization:

• SIP-aware firewalls and SBCs configured to support NAT traversal, secure SIP signaling, and media anchoring for consistent call flow.
• Voice VLAN design separating signaling and RTP streams for predictable bandwidth management and faster troubleshooting.
• Dynamic Call Admission Control (CAC) and SRTP/TLS encryption for secure and reliable VoIP transmission across distributed offices.
• Monitoring and diagnostics with Cisco Prime, NetFlow, or SolarWinds to track MOS scores, packet loss, and latency for proactive voice assurance.
• Integration with Cisco Unified Communications Manager (CUCM) and hybrid IP-PBX platforms to extend enterprise-grade voice services to the network edge.

Business Benefits:

• Uninterrupted communication through dual ISP links, redundant routing, and high-availability topologies.
• Crystal-clear VoIP quality across offices, branches, and remote endpoints via QoS and Cisco Unified Communications tuning.
• Reduced downtime and faster recovery with intelligent failover, modular upgrades, and proactive monitoring.
• Secure, scalable architecture ready for cloud voice, hybrid UC, and collaboration platforms.
