Reduce Costs with Per-Second Billing

By adopting our SIP Trunking service, you pay only for the seconds you actually use. This flexible billing approach often translates to significant cost savings over conventional fixed-rate plans. Control your budget more accurately and redirect resources to more critical aspects of your business.

How the Per-Second Billing System Works

When using a 0120 number (Toll-Free for the caller, charged to the receiver) …

In a flat 3-minute billing system (¥10.5 per 3 minutes)

Caller dials: 0120-ABC-DEF
Talks for 50 seconds → operator answers
Billed as a full 3-minute unit (180 seconds)

Even a 50-second call gets billed for a full 180 seconds, including 130 seconds of unused time.

→ Total charge: ¥10.5

With SIP Trunk + per-second billing (e.g., LIPSE: ¥0.06/sec)

Caller dials: 0120-ABC-DEF
Talks for 50 seconds
Only the 50 seconds are billed

You only pay for actual call time—no charge for idle time.

→ Total charge: ¥3.00

Reduce costs to less than one-third with per-second billing, even short calls result in significantly lower charges.
