The Institute of Singapore Chartered Accountants (ISCA) is the national accountancy body of Singapore, representing over 40,000 members across 40 countries. Established in 1963, ISCA advocates for the interests of the accounting profession, complements global standards with Asian insights, and plays a key role in advancing accountancy practices across industries. It administers the Singapore Chartered Accountant Qualification (SCAQ) and is the Designated Entity to confer the Chartered Accountant of Singapore – CA (Singapore) designation.

ISCA’s previous telephony setup — a vendor-hosted IP-PBX that combined unified communications and contact centre functions — met the organisation's basic needs but lacked flexibility as its requirements evolved.

 

Routine changes, such as ad-hoc closure messages or call routing updates, required vendor involvement and incurred additional costs. These requests often took up to three days to process, resulting in delayed responses to members and internal teams.

 

ISCA needed a solution that would streamline system administration and call handling, reduce dependency on external vendors, and more efficiently and securely support its evolving communication needs.

 

To address these challenges, ISCA adopted Zoom Phone and Zoom Webinars as part of its digital transformation journey.

Empowering internal agility with Zoom Phone

With Zoom Phone, ISCA has more control over its telephony environment. Administrative tasks, such as provisioning, routing, and call handling, can now be managed internally — reducing delays and reliance on vendors.

 

ISCA administrators and phone users can now customise call handling settings to determine how calls are routed during business hours, breaks, holidays, or out-of-office periods. What previously required raising a support ticket and waiting three days can now be done much faster, saving valuable time and improving responsiveness.

The platform’s SAML SSO integration also simplifies onboarding for new employees, while Bring Your Own Carrier (BYOC) capabilities provide added flexibility and cost efficiency.

Expanding reach and engagement with Zoom Webinars

ISCA’s marketing team first began using Zoom Webinars during the pandemic period to conduct virtual info sessions for accounting professionals. Since then, webinars have become an integral part of ISCA’s hybrid event strategy, allowing the organisation to connect efficiently with both local and overseas members.

 

Through Zoom Webinars, ISCA has successfully connected over 500 participants in the past year and continues to reach members across Southeast Asia and China.

 

Improved outcomes include:

  • Better international outreach to members abroad.
  • Flexible attendance options — professionals can join sessions during lunch, after work, or while commuting.
  • Increased participation and engagement across events.
