AI-powered call center gateway
for sales teams in India
A SIP/GSM gateway that records every sales call, transcribes it in real time, and generates accurate quotations automatically. Your sales team spends less time on paperwork and more time closing deals.
What you are dealing with today.
Sales reps mis-quote pricing on calls
When reps handle 40+ calls a day, they misremember product codes, apply wrong discounts, or skip line items. Inaccurate quotes cost you margin and credibility with buyers.
Quotation turnaround is too slow
After a call, the rep writes notes from memory, opens a spreadsheet, looks up pricing, and emails the quote. This takes 20-45 minutes per quote. Buyers move on to competitors who respond faster.
No visibility into what reps actually say on calls
Managers have no way to know if reps follow the script, offer unauthorised discounts, or miss upsell opportunities. Call quality is a black box until a customer complains.
From setup to results.
Connect the gateway to your PBX or SIP trunk
The gateway sits between your PBX and your telecom lines. It supports SIP trunks, PRI lines, and GSM SIMs. Installation takes under a day with zero disruption to ongoing operations.

Calls are recorded and transcribed in real time
Every outbound and inbound call is recorded in full. The built-in AI engine transcribes speech to text in Hindi, English, Tamil, Telugu, and Marathi with over 90% accuracy.

AI Call Center Gateway in 60 seconds.
What it looks like in practice.
Building materials distributor, Coimbatore
A 45-seat outbound sales team was quoting over the phone for cement, steel, and plumbing products. Reps were handling 50+ calls daily but quoting from memory, leading to pricing errors on nearly a third of all quotations. Incorrect quotes caused margin leakage and eroded buyer trust.
After deploying the AI Call Center Gateway, auto-generated quotes reduced pricing errors from 30% to under 6%. Time-to-quote dropped by 65%, from an average of 35 minutes to 12 minutes per quote.
"Our reps used to spend half their time building quotes in Excel. Now the system drafts the quote before they hang up. We are closing faster and losing fewer deals to competitors who used to beat us on response time."Rajesh K., Head of Sales, Building Materials Distributor
