Enterprise-Grade Security Controls
Encryption at rest and in transit, role-based access, audit logs, and controls built to meet HIPAA, PCI DSS, and GDPR requirements.
Enterprise-grade security, compliance, SLAs, and dedicated support for organizations that can't afford downtime or compromise.
Large organizations need more than just features - they need security, compliance, reliability, and support to match their scale.
Healthcare, finance, and regulated industries can't afford data breaches or compliance failures. Your current vendor's security posture and certifications may not meet your standards.
For your contact center or sales organization, phone system downtime means immediate revenue loss and customer dissatisfaction. You need guaranteed uptime and rapid incident response.
On-premise PBX hardware is aging out. You need to move to the cloud, but your requirements around data sovereignty, failover, and integration complexity make migration risky.

Mission-critical customer engagement
Your contact center handles hundreds or thousands of agents across multiple sites and time zones. Downtime is not an option. You need advanced ACD, workforce management integration, quality monitoring, and the reliability to support your customer commitments.
Compliance-first communications
Healthcare, financial services, and government organizations have strict requirements around data security, retention, and auditability. You need a vendor who understands compliance isn't optional.
Unified communications across continents
Your organization operates in 20+ countries with regional headquarters, remote offices, and distributed teams. You need one unified communications platform that works everywhere with local support.
Enterprise deployments start with a discovery workshop to understand your requirements, integrations, and success criteria. We assign a dedicated solution architect and project manager. Typical timeline is 60-90 days for large deployments, including pilot testing, phased rollout, training, and hypercare post-launch support.
Our infrastructure follows security best practices. We are HIPAA-ready and support PCI DSS and GDPR requirements. We can provide security questionnaires, documentation, and participate in vendor security reviews. Our security team can discuss your specific requirements including penetration testing, vulnerability scanning, and incident response procedures.
Our published SLA is 99.95% uptime, with custom targets available for mission-critical deployments. SLA includes financial credits for downtime, guaranteed support response times (15 minutes for P1 issues), and proactive monitoring. We can customize SLAs based on your specific requirements.
Our infrastructure is geo-redundant across multiple availability zones and regions. Automatic failover happens within seconds if a data center goes offline. We support customer-defined business continuity plans including failover to PSTN, mobile apps, or alternate sites. We conduct DR testing annually and can participate in your DR drills.
Enterprise pricing is custom based on user count, usage patterns, required integrations, and SLA terms. We offer multi-year commit discounts, volume pricing tiers, and flexible billing terms (monthly, quarterly, or annual). Your account team will work with you to structure pricing that fits your budgeting and procurement requirements.
