Introduction

The web-based Phone System enables seamless contact management and ensures data accuracy. It includes built-in support for importing and exporting contact lists, making it easier to maintain up-to-date information.

How to import / export and add new contact

Go to Phone System - View Me
Click on Import, then upload the contact list (.csv or .vcf)
Click on Export the contacts to get existing contact list
Click on Add to add new contact
- When a regular country code is selected, only digits are accepted and the selected country code is added to the number.
- When No prefix is selected, the number is saved exactly as entered without adding a country code. The field accepts digits together with +, *, and #.

Option	Accepted input	Example
Country code selected	Digits only	`12345678` with `+65` → `+6512345678`
No prefix	Digits, `+`, `*`, `#`	`*69`, `#123`, `1001`

Important Notes

Select No prefix only when the number should not use a standard country code.
Regular country-code numbers continue to work exactly
With No prefix, the system supports service-style numbers such as *69, #123, or extension numbers such as 1001.
This feature is supported consistently across Web, Desktop, and Mobile.

Limitations

Maximum numbers which can be added to Contacts = 10,000 numbers
Existing contacts + New import contacts ≤ 10,000. If exceeded, the upload will be blocked with appropriate error message.
If an imported number already exists, the system replaces the existing record with the new one.

Existing Contacts	Import File Size	Allow Upload?	Message
0	10,000	✅	Imported successfully.
1	9,999	✅	Imported successfully.
1,000	10,000	❌	You have 1,000 contacts. Uploading this file will exceed the 10,000 limit. Please reduce your file and try again.
10,000	Any number	❌	You’ve reached the maximum limit of 10,000 contacts.
