Why the phone matters for translation and interpretation services

Translation and interpreting agencies coordinate linguists for appointments, court dates and document deadlines, so many calls are about scheduling and availability. Fast replies win time-sensitive requests.

Calls translation and interpretation services commonly handle:

• A clinic calls to book an interpreter for tomorrow.
• A law firm calls about translating documents for a filing.
• An interpreter calls to confirm an assignment.
• A client calls to ask about certified translation.
• The agency calls a client with a quote.

Texting and after-hours calls

Agencies text assignment confirmations to interpreters and clients.

Requests for next-day interpreters often arrive late in the day, so capturing them quickly matters.
