Chitkara University runs a large, multi-department campus with heavy daily call traffic for admissions, administration, and student services.
To ensure reliability, the university had two independent SIP trunk lines from Jio.
Yet—
both SIP trunks were idle.
Despite multiple attempts, the university’s existing IP-PBX could not successfully configure or route calls over these SIP trunks.
Two separate Jio SIP trunks, each behaving differently
No ready-to-use SIP profiles
Manual configuration attempts caused:
Registration failures
One-way audio
Calls not routing as per policy
Vendor documentation was complex and slow to implement
Result:
❌ SIP trunks not usable
❌ Delayed go-live
❌ Rising dependency on telecom support
Nexbro changed the game with preconfigured SIP trunk templates built specifically for Indian telecom operators.
No manual tweaking.
No guesswork.
No delays.
✔ Recognized both Jio connections as independent logical SIP trunks
✔ Applied ready-made Jio SIP templates
✔ Auto-configured authentication, codecs, NAT, and routing
✔ Implemented custom call flow rules as required by the university
Nexbro is designed with one clear philosophy: Telephony should be effortless. Our SIP engine comes with carrier-specific intelligence — so when a SIP trunk is connected, Nexbro already knows how to talk to it.
Nexbro handles multiple SIP trunks, multiple providers, and complex routing — without complexity.
