Rapid SIP Scaling for Business Continuity: Supporting the World’s Largest International Airline

The airline faced 3 critical challenges:

• Capacity constraints: Existing SIP Trunking capacity of sessions was insufficient to accommodate the sudden increase in call volumes.

• Time-critical scalability: Conventional capacity expansion timelines of approximately 7 days were not viable during an immediate operational crisis.

• Business continuity risk: Any inability to handle the increased traffic could have resulted in service degradation, customer support bottlenecks and potential disruption to global operations.

Vi Business worked closely with the airline to assess the immediate capacity requirement and develop an accelerated implementation plan. The solution was designed around speed, scalability and operational continuity:

• Rapid Capacity Expansion: SIP session capacity was increased 4x to support the surge in call centre traffic.

• Infrastructure Optimisation: Existing network paths were leveraged to enable the capacity upgrade without requiring additional hardware deployment or complex infrastructure changes.

• Rapid Technical Assessment: Technical feasibility for the Mumbai and Hyderabad locations was completed in under 30 minutes, enabling implementation to move ahead immediately.

• Zero-Disruption Implementation: The capacity expansion was executed during an overnight maintenance window, with validation completed in near real time to ensure continuity of business operations.

The rapid capacity expansion strengthened the airline’s ability to maintain uninterrupted customer support during a period of exceptional demand.

• 4X Increase in Capacity: SIP capacity was expanded 4 times, enabling the airline to handle a significant increase in global call traffic.

• 16-Hour Implementation: The complete capacity upgrade across Mumbai and Hyderabad was successfully delivered in approximately 16 hours.

• 90% Faster Turnaround: The implementation was completed more than 90% faster than the standard seven-day provisioning timeline, enabling the airline to respond to a rapidly evolving situation in near real time.

• Protection of Revenue and Customer Relationships: Maintaining continuity across global call centre operations helped minimise the risk of revenue loss, customer dissatisfaction and reputational impact associated with service interruptions.
