Your customers live in apps, your teams live on laptops, your voice still lives in racks. When a PRI fills up in Mumbai, calls spill. When a fibre drops in Pune, a store goes dark. Cloud calling fixes capacity, resilience, and change control with SIP, SRTP, and a console your admins can run.
Enterprise telephony delivered from the cloud. You connect by SIP trunks or cloud PSTN, secure signalling with TLS, secure media with SRTP, and manage numbers, queues, recording, and policy from one web console. It replaces PBX controllers and PRI circuits and adds APIs for CRM and contact centre.
Supervisors in Noida coordinate with plants in Chakan and Sriperumbudur. Move voice to Webex Calling, terminate SIP with dual carriers via certified SBCs, and keep a survivability gateway at the plant edge. Enforce MOS targets for shopfloor calls, loss under 1%, jitter under 30 ms. Bilingual IVR routes dealer calls, and call recording supports traceability under ISO audits. Outcome to aim for: faster shift hand-offs and quicker line recovery.
Hospitals in Bengaluru and Hyderabad need encrypted recording and audit trails without complex racks. Use Indian media anchoring, TLS and SRTP by default, role-based access, and retention controls tied to policy. Integrate with EHR via webhooks or connectors so clinicians see context during calls. Target patient callback time reduction and sub-10-minute audit retrieval. Independent regulators confirm the shift from TDM to IP voice is irreversible, source: Ofcom PSTN programme.
Service desks and delivery teams in Gurugram, Pune, and Chennai run mixed devices and ISPs. Cloud calling gives a consistent layer with SSO, MFA, and per-user quality metrics. Use CRM screenpop, autodial, and call analytics to cut average handle time. Set health thresholds per site, then steer calls across carriers when loss or jitter rises. Track changes with audit and keep a survivability option for critical floors.
Wealth and brokerage desks in Mumbai and Ahmedabad need retention, lawful intercept readiness, and tamper-evident logs. Use encrypted recording with policy-driven retention, anchor media in India, and stream logs to your SIEM. Port DIDs in phases so traders never lose line state. Aim for 100% recording on regulated users and audit pulls under ten minutes. Industry analyses show that outages and slow responses inflate incident costs.
Stores across India need a working voice on day one. Push templates, assign numbers, and bring sites up over broadband or LTE, then cut to fibre. Use IVR to route customer and vendor calls by language and region. Monitor MOS and answer rates at peak, and adjust queues quickly. A practical target, reduce store turn-up from three days to one and drop missed calls during shift change.
If you run one site, have sunk PBX cost, stable call volumes, and hard analogue ties for another year or two, waiting can be practical. For netnew sites or any multi-city plan, cloud calling wins on time, risk, and operating cost.
It removes PBX hardware limits, makes capacity elastic, improves resilience with multi-region platforms, and lets admins change dial plans and queues in minutes with audit and SSO.
Either through cloud PSTN from the provider or through your telco via certified SBCs. Port existing DIDs in phased windows, keep interop with the PBX during cutover.
Peruser MOS, packet loss, latency, jitter, answer rates, average handle time for contact centres, time to open sites, and change failure rate.
Ask for Indian points of presence, encrypted signalling and media, lawful intercept readiness, role-based access, retention controls, and full change audit. Enforce MFA for admins.
Pilot in days, phased porting over weeks. Sites can go live in a week with templates, LTE fallback, and a simple test script.
As a Cisco Gold Partner, Proactive designs PBX exit plans and greenfield rollouts across metros and tiertwo towns. We plan hybrid periods with clean routing between old and new dial plans, set quality thresholds your NOC can run, and leave a runbook your team owns.
Move from racks to a console you control.
