Survey Finds "Line and Hikari Denwa" a Key Topic in 1 in 3 Business Phone Consultations

OFFICE110 (operating company: Bell-technos Co., Ltd.) analyzed 534 anonymized business phone-related inquiries received between December 7, 2022, and February 28, 2026, to understand the concerns and confirmation items companies have when introducing business phones.

The results showed that cases including "line and Hikari Denwa" in the consultation content amounted to 179, or about 33.5% of the total. Furthermore, 73 consultations (13.7%) were classified with "line and Hikari Denwa" as the central theme.

This survey indicated that the decision to implement business phones is not determined solely by the "price of phones" or "choice of models," but is also related to confirming the existing Hikari Denwa, main numbers, FAX, main units, wiring, and construction conditions.

Even as smartphone use becomes more common, main numbers, FAX, and call transferring do not simply disappear. This is not just a matter of choosing a phone, but an issue directly linked to the business continuity of small and medium-sized enterprises (SMEs).

**Summary** - "Line and Hikari Denwa" is a topic in about 1 in 3 business phone consultations. - The implementation decision is not made on "price" or "model" alone. - SME managers need to confirm line, number, FAX, and wiring conditions before getting a quote.

**"Line and Hikari Denwa" a Topic in About 1 in 3 Business Phone Consultations**

In recent inquiry data submitted to OFFICE110, 179 cases were confirmed to include "line and Hikari Denwa" in the consultation content. This accounts for approximately 33.5% of the 534 cases analyzed.

Additionally, 73 consultations (13.7%) were classified with "line and Hikari Denwa" as the central theme. This indicates that handling existing lines and Hikari Denwa is one of the main deciding factors in business phone implementation.

**Pre-implementation Anxiety Not Solved by Just "Choosing a Cheap Phone"**

Concerns about business phone implementation are focused not just on price, but on whether existing lines can be utilized.

In actual consultations, while choices between new and used, the number of phones, initial costs, and monthly fees are often compared, issues of existing lines, main numbers, FAX, main units, wiring, construction costs, and maintenance conditions arise simultaneously.

In potential FAQ topics from recent inquiry data, "What to do about the line?" was confirmed in 103 cases, "How much is the construction cost?" in 123 cases, and "How many units are needed?" in 257 cases. This shows that company managers are not simply looking for "cheap models," but are confirming whether they can implement a system while maintaining their existing phone environment and how the total cost will change, including construction and setup.

**Maintaining Existing Lines, FAX, and Numbers is Related to SME Business Continuity**

Even with the spread of smartphones, main numbers, FAX, and call forwarding are not easily eliminated.

In many SMEs, main and FAX numbers have been used for many years. Since these numbers are linked to business partners, customers, websites, business cards, invoices, and various registered information, changing a number is more than just a change in a communication contract.

Particularly in industries that use FAX, ordering, applications, and confirmation processes may be tied to phone lines. While consideration of smartphone integration and cloud PBX is advancing, how to retain main numbers, FAX, and call transfer operations remains a critical point of discussion for implementation decisions.

**Postponing Line Confirmation Can Change Quotes and Construction Conditions**

A business phone is not a standalone piece of equipment. The main unit controls external lines, internal lines, hold, transfer, FAX, and main numbers. Therefore, even when using Hikari Denwa, it is necessary to confirm the main unit's compatibility, necessary units, wiring status, installation location, and construction schedule.
