IP phones (VoIP desk phones) run over your office LAN and connect to a SIP PBX or hosted VoIP provider — replacing legacy analog PABX handsets with HD voice, multi-line support, colour LCD screens, and free extension-to-extension calling across branch offices. CSL Systems distributes Yealink, Fanvil, Grandstream, Cisco, and Cortelco IP phones from our Dhaka office, with same-day pickup or nationwide courier via Sundarban, SA Paribahan, and RedX.

Pair with an IP PBX: we stock Yeastar S20/S50/S100 series (analog + SIP hybrid), Grandstream UCM6304/UCM6308, and Fanvil IP PBXes. Existing analog PABX (IKE, Panasonic KX-TES824, NEC) can also be extended by adding a FXS/FXO VoIP gateway — no need to rip out working infrastructure.

All phones ship with valid Bangladesh warranty and support the SIP standards used by every mainstream PBX and hosted VoIP provider — including local providers like Amber IT, ADN Telecom, BTCL SIP trunk, and BSCCL SIP. Our engineers configure the phone for your PBX before dispatch if you provide the SIP credentials — plug in Ethernet, plug in PoE, done.
