Installation & Setup Questions
How long does a typical corporate VoIP installation take?
Most standard SME installations (10 to 50 extensions) are fully deployed within 24 to 48 hours. Number porting is scheduled at an agreed time so there is zero interruption to your live telephone lines.
Do we need new cabling in our offices?
In most cases, no. Modern IP desk phones feature dual-port Gigabit passthrough switches, allowing your computer and telephone to share a single existing Ethernet wall port. Wireless DECT and Wi-Fi IP phones are also available.
Can our existing analog fax and door phones continue working?
Yes. By deploying specialized Analog Telephone Adapters (ATA gateways), traditional fax machines, alarm lines, and building intercoms are cleanly incorporated into the modern VoIP platform.
What technical support is provided after installation?
infoLib provides proactive 24/7 PBX health monitoring, software updates, automated offsite backups, and guaranteed SLA response times for any moves, adds, or changes.
