This is a real-world bill of materials for a 10-person office in Bergen moving from mobile-only or a single landline to proper business VoIP.

SIP trunk: 8 concurrent channels with 2 Norwegian DIDs — enough for 10 staff if not everyone phones at once. VoiShop Business plan at 899 NOK/mo covers this with headroom.

Hardware: you don't need 10 desk phones on day one. Start with 2 IP Phone Pro units (1 490 NOK × 2 = 2 980 NOK) at reception and the busiest desk. Everyone else uses the softphone app until you expand.

Network: a basic PoE switch (if your router lacks PoE) runs 800–1 500 NOK. Most small offices already have adequate switches — check before buying.

Setup: zero-touch provisioning means phones pull config automatically. Budget an afternoon for firewall rules, QoS tagging, and testing emergency numbers (112/113/110 must work — verify with your provider).

Total first-month cost: 899 NOK trunk + 2 980 NOK phones ≈ 3 879 NOK upfront-ish, well under 15 000 NOK. Or grab the Office VoIP Kit at 12 990 NOK for a bundled 10-seat package with phones, trunk, and a setup guide included.

Scale path: add phones as desks get permanent assignments, add channels when busy-hour tests show congestion, port your main +47 number once you're confident in uptime.
