Business communications

Why switch to IP telephony?

IP telephony (VoIP) carries calls over your data network. With an IP PBX you get extensions up to its capacity, an auto-attendant (IVR), call recording, voicemail, conferencing, and the ability to answer from your phone or computer.

At LAN EL SALVADOR we install and configure Grandstream, 3CX, and Asterisk IP PBXs and Yealink, Grandstream, and Fanvil phones, and integrate SIP lines from national and international carriers. If you already have PoE switches, the phones are powered over the same network cable.

Frequently Asked Questions

Common questions about IP telephony

Do I need to change my cabling to use IP telephony?
Normally not. IP phones connect to the existing data network. If your switches have PoE, the phone is powered over the same cable; if not, an adapter or a PoE switch can be used.
Can I keep my current phone numbers?
In many cases, yes, either by connecting your current lines to the PBX through FXO ports or by arranging number portability or SIP lines with your carrier. We assess it during the site visit.
How many extensions can I have?
It depends on the PBX. The solutions we install can scale from 5 to over 500 extensions without changing platforms.
What happens if the internet goes down?
Internal calls between extensions keep working within your local network. External calls depend on the configured lines; an analog backup line can be left connected to the PBX.
Can I answer calls from my mobile phone?
Yes, with a softphone your extension works on Android, iOS, or your computer, in or out of the office, securely.
