Pure IP: Seamless Global Voice and Cloud Telephony Solutions

Welcome to the Enterprise Evaluation Guide for Pure IP. As organizations transition away from traditional on-premises telephony toward cloud-based unified communications (UC), selecting the right voice service provider becomes a critical infrastructure decision. Pure IP stands out in the market as an engineering-led global voice specialist, offering SIP trunking and managed voice services that bridge the gap between legacy systems and modern platforms like Microsoft Teams, Zoom, and Cisco Webex.

This guide is designed to provide IT leaders, network architects, and procurement professionals with a technical and strategic overview of Pure IP’s offerings. You will learn about their global coverage, the unique 'SeRVE' management platform, and how their solution fits into complex, multi-national enterprise environments. By the end of this guide, you will have the necessary criteria to determine if Pure IP is the right partner to simplify your global voice estate and enhance your communication reliability.

Pure IP’s value proposition is centered on global reach and technical reliability:

• Global SIP Network: A single, resilient global voice network covering 45+ countries with full PSTN replacement and over 137 countries for numbering, reducing the need for multiple local carrier contracts.
• SeRVE Management Portal: A proprietary 'single pane of glass' dashboard that allows administrators to manage numbers, view real-time call analytics, monitor trunk health, and access billing across all global locations.
• Multi-Platform Support: True platform agnosticism, allowing for the simultaneous support of Microsoft Teams, Zoom, and Cisco Webex on a single SIP backbone.
• Managed Migrations: Expert-led porting and migration services that handle the complex regulatory and technical hurdles of moving numbers from legacy carriers.
• Disaster Recovery & Redundancy: Built-in automated failover routing and geo-redundant secondary nodes to ensure 99.999% uptime for business-critical voice services.
• Number Management: Comprehensive services for acquiring new DIDs, porting existing numbers, and managing toll-free and emergency services (E911) globally.

How organizations utilize Pure IP:

• Scenario 1: The Microsoft Teams Transition. A global manufacturing firm moves from an Avaya PBX to Microsoft Teams. Pure IP provides 'Operator Connect' for simple offices and 'Direct Routing' for complex factory sites, all managed through one portal.
• Scenario 2: Global Contact Center Consolidation. A financial services company with call centers in the US, Philippines, and Poland consolidates its SIP providers. Pure IP provides local toll-free numbers and high-capacity trunks that integrate directly with their Genesys cloud platform.
• Scenario 3: Hybrid Cloud Coexistence. A university wants to keep its legacy analog campus phones while moving the faculty to Zoom Phone. Pure IP creates a hybrid SIP architecture that allows for extension-to-extension dialing between the old and new systems.
• Scenario 4: Rapid Market Entry. A tech startup expands into Brazil and Japan. Instead of dealing with local telecom bureaucracy, they use Pure IP to instantly provision local numbers and PSTN access via the cloud.

Pure IP typically employs a consultative pricing model tailored to enterprise needs:

• Consumption-Based (Per Minute): Ideal for organizations with fluctuating call volumes, where you pay only for the outbound minutes used.
• User-Based (Unlimited Bundles): Predictable monthly per-user pricing that includes a bucket of minutes for domestic and/or international calling.
• Channel-Based Pricing: Based on the number of concurrent call paths required, common for high-volume contact centers.
• One-Time Costs: Typical fees include number porting charges, initial setup/activation fees, and professional services for complex migrations.
• Tiered Discounts: Volume-based discounts are generally available for large enterprises with high seat counts or significant global minute requirements.

To deploy Pure IP, the following technical components are required:

• Certified SBCs: For Direct Routing, a certified Session Border Controller (e.g., Ribbon, Audiocodes) is required, though Pure IP can provide these as a managed service.
• SIP-Compliant Endpoints: IP phones or softphones that support standard SIP protocols (if not using a cloud platform like Teams).
• Bandwidth: Approximately 100kbps of symmetrical bandwidth per concurrent call (using G.711 codec).
• Firewall Configuration: Ability to open specific ports (typically UDP 5060/5061) and whitelist Pure IP’s signaling and media IP ranges.
• DNS: Access to manage public DNS records for SRV record configuration in some deployment scenarios.

To successfully implement Pure IP, organizations should meet the following business prerequisites:

• Telephony Governance: A clear understanding of existing global phone number inventories and contractual obligations with current carriers to manage the porting process.
• Stakeholder Buy-in: Alignment between IT/Infrastructure teams and the business units (e.g., Customer Success, Sales) that rely on uninterrupted voice services.
• Project Management: Dedicated internal resources to coordinate with Pure IP’s technical team during the discovery and porting phases, particularly for global deployments.
• Network Readiness: A business-grade internet connection or dedicated circuit (SD-WAN/MPLS) with prioritized Quality of Service (QoS) for voice traffic.
• Regulatory Knowledge: Awareness of local emergency services (E911/L-911) requirements in the regions where services will be deployed.

A typical Pure IP implementation follows these phases:

• Discovery & Design (Weeks 1-2): Technical audit of existing infrastructure, number inventory collection, and architecture design (e.g., Direct Routing vs. Operator Connect).
• Configuration & Account Setup (Weeks 2-3): Setting up the SeRVE portal, configuring SIP trunks, and establishing secure connections (TLS/SRTP).
• Testing & Pilot (Weeks 3-4): Inbound/outbound call testing, emergency services verification, and a limited user pilot to ensure audio quality.
• Number Porting (Weeks 4-12+): This is the most variable phase. Simple ports in the US/UK can take days, while complex international ports or 'managed migrations' in regulated markets can take several months.
• Go-Live & Handover (Week 1 of launch): Full transition to the new environment and training for administrators on the SeRVE management portal.

Pure IP is known for its "engineering-first" support culture:

• 24/7/365 Technical Support: Round-the-clock access to technical engineers (not just first-level agents) located in global hubs (UK, USA, Australia).
• Follow-the-Sun Model: Support tickets are transitioned between global offices to ensure continuous progress on critical issues.
• Dedicated Account Management: Enterprise customers are typically assigned a dedicated account manager for strategic planning and business reviews.
• Online Knowledge Base: Access to technical documentation, configuration guides for various PBXs, and portal user manuals.
• Professional Services: Paid engagements for custom solution design, complex site migrations, and on-site hardware configuration if required.

Pure IP is built on an 'agnostic' philosophy, offering deep integration capabilities:

• Certified Cloud Platforms: Deep, native integration with Microsoft Teams (Operator Connect & Direct Routing), Zoom Phone (Cloud Peering), and Cisco Webex Calling.
• API Access: RESTful APIs are available for customers to automate provisioning, pull billing data into ERPs, or integrate call data into custom dashboards.
• Legacy Hardware: Support for Analog Telephone Adapters (ATAs) and Gateways to integrate fax machines, overhead pagers, and older PBX systems.
• Contact Center: Compatible with major CCaaS providers (e.g., Five9, Genesys, Nice CXone) via SIP peering.
• Interoperability: Support for standard SIP protocols, ensuring compatibility with virtually any standards-based IP-PBX or softphone.

Pure IP prioritizes enterprise-grade security and regulatory adherence:

• Encryption: Support for TLS (Transport Layer Security) and SRTP (Secure Real-time Transport Protocol) to ensure voice traffic is encrypted in transit.
• Certifications: Adherence to international standards, including ISO 27001 for information security management.
• Data Residency: Options to ensure call signaling and data remain within specific geographic regions to satisfy local data sovereignty laws (e.g., GDPR).
• Fraud Prevention: Real-time monitoring for suspicious calling patterns with automated alerts and threshold-based blocking to prevent toll fraud.
• Network Security: Redundant SBCs (Session Border Controllers) acting as a firewall for voice traffic, protecting the internal network from external threats.
