Product - GSM/FXO gateway trunking

Your SIM is your trunk.

A Dinstar gateway turns the SIM cards and landlines you already pay for into your business lines. No DID paperwork, no per-minute markup, no porting - the numbers your customers know just work.

How it works

SIM in. Dial tone out.

01 Your SIMs & landlines The Jio, Airtel or BSNL numbers your business already owns
02 Dinstar gateway GSM slots and FXO ports become SIP trunks on your LAN
03 Wivox server Routes them through IVR, queues, recording - like any trunk
04 Every phone Desk phones and apps ring on GSM calls; staff dial out over your SIMs

Hardware

Sized to your line count.

Dinstar gateways are sold per port. Start with 4 GSM slots; a hotel or call-heavy office can run 32. Mix GSM and FXO freely - the PBX treats both as lines.
