Frequently asked questions
IP-PBX and EPABX questions
Clear answers to common planning and selection questions.
What is the difference between EPABX and IP-PBX?
An EPABX connects analog or digital phones over telephone cable. An IP-PBX runs on your office network with IP phones, mobile apps and SIP trunks. A hybrid system supports both, so you can upgrade in stages.
How many outside lines do I need?
A common starting point is one outside line for every 6–8 extensions. Busy reception desks and call centres need more. Zerolink sizes trunks from your actual call pattern.
Can staff answer office calls on their mobile?
Yes, with an IP-PBX or a hybrid system that supports a mobile softphone app. Calls ring the desk phone and the app together.
Will the phones work during a power cut?
Only if the PBX, switch and gateways are on UPS backup. Zerolink includes power backup and a GSM or analog fallback line in the design when continuity matters.
