#1 Please note that our SIP line only guarantees to call to 2 types of toll-free:

  • International toll-free Singapore 800 (It can be reached from overseas)

  • Local toll-free Singapore 1800 (can only be reached from Singapore)

Besides, we have not supported calling to other emergency DIDs such as 993,995,997,1777 at this time.


We are trying to improve on this case, also we will keep update to you when it's available.


#2 Kindly remember to dial prefix +65 before toll free 1800 xxx xxxx


Alternatively, you configure the portal to append +65 in order to dial 1800xxxxx only.


However, then when you dial a US number, it will also append +65 and may cause a call fails.


This can be set under the SIP app -> Dial Plan. ( you can refer the screenshot below)

  • For 1800, they need to set: Number starts with 1800 Length of 11 Then prepend 65

  • For 800, they need to set: Number starts with 800 Length of 10 Then prepend 65
