Expected Outcomes and Requirements

• Own voice orders from post-sale handoff through installation and closeout. Validate sales handoff information, confirm the ordered services and customer contacts, and resolve missing or inconsistent details with the appropriate teams.


• Lead customer discovery and collect complete call-flow requirements, including users and extensions, call routing, business hours, voicemail, auto attendants, and ring groups. Document and confirm the intended configuration with the customer.


• Create and maintain secure, organized customer folders containing order details, call-flow documentation, porting records, implementation communications, and testing results. Keep documentation current and accessible to authorized internal teams.


• Serve as the primary customer contact during implementation, communicate next steps and customer responsibilities, and provide timely updates on progress, milestones, schedule changes, and issues.


• Track order status, dependencies, and blockers through installation. Coordinate with sales, technical teams, commercial order management, field technicians, and external providers to keep work aligned and elevate risks to timely completion.


• Manage number porting by collecting and validating letters of authorization (LOAs), customer service records (CSRs), and accurate telephone number lists. Coordinate carrier submissions, resolve discrepancies, confirm port dates, and communicate the transition plan so customers do not cancel existing service before porting is complete.


• Coordinate provisioning and readiness checks against the approved order and call flow. Confirm service, equipment, and customer readiness with the responsible teams, and schedule installation in alignment with customer availability and confirmed porting dates.


• Coordinate call-flow validation and customer acceptance testing at installation. Track issues to resolution, complete the handoff to commercial support team with current documentation, and close the order after confirming completion with the customer and internal teams.


• Troubleshoot and resolve problems across VoIP, fiber, fixed wireless, routing, switching, and related network services, coordinating changes with the responsible technical teams.


• Perform in-depth analysis using packet capture, signaling trace, and diagnostic tools.


• Collaborate with internal teams and external vendors and carriers to identify and resolve root causes of phone and network issues.


• Participate in outage response and incident management, ensuring accurate communication and timely resolution.


• Document troubleshooting steps, processes, and solutions for use across the support team.


• Recommend process improvements for monitoring, escalation, and service reliability, and implement approved improvements in coordination with the appropriate teams.


• Ensure compliance with SLAs and company standards for customer service and response times.


• Serve as an advanced escalation resource for commercial voice-service issues that exceed established frontline troubleshooting procedures.


• Provide technical guidance regarding provisioning anomalies, carrier disputes, signaling issues, Hosted PBX configuration, call-flow design, and related voice-service concerns.


• Coordinate advanced troubleshooting efforts with carriers, vendors, Network Operations, Engineering, and other technical resources when required.


• Provide backup support for routine residential number-porting, voice activation, and service-activation activities during periods of staffing constraints, elevated workloads, or other operational needs.


• Support residential operations by assisting with provisioning validation, activation troubleshooting, status review, customer communication, and workflow completion consistent with established procedures.


• Maintain sufficient cross-training on residential activation and provisioning workflows to support operational continuity without assuming primary ownership of residential operations.


• Stay current on emerging Hosted PBX products, features, and vendor offerings; evaluate their customer value, technical fit, and operational requirements, and provide recommendations to leadership for consideration.


• Develop and deliver Hosted product training for internal teams, including customer service, support, and sales. Partner with the Sales Engineer to train sales teams on product capabilities, use cases, requirements, and limitations, helping ensure accurate customer expectations and complete implementation handoffs.
