Understanding VoIP Call Blocking to Singapore
Why are Singapore telecoms blocking my VoIP calls from Zendesk Sell?
Singapore telecoms block VoIP calls from Zendesk Sell due to strong anti-fraud measures. These measures are part of the "Implementation of Measures to Address Spoofed Calls" regulatory code, which was introduced in 2020.
This regulation means that calls can only be made on a best-effort basis, affecting the ability to make outgoing calls to Singapore. To overcome this, you can purchase a Singapore National number, which requires document verification and can take up to three weeks to be delivered. For more information, you can refer to the originalZendesk article.
