Business phone service / Singapore
Business phone service for Singapore regional headquarters.
Singapore is the regional base for many companies covering Southeast Asia, with staff who travel, teams in several time zones and customers who call in English, Mandarin, Malay and more. Texwan sets up phone systems remotely, programs phones before they ship and makes sure everyone knows what their number type can and cannot do.
Singapore numbers come from IMDA-licensed providers, where available. We work remotely and do not claim a Singapore office or licence.

Threat Briefing
IMDA’s IP telephony framework uses Level 6 numbers, which must provide free access to 999 and 995 and number portability, and Level 3 numbers, which do not have to offer emergency access but whose users must be told. (IMDA)
The number type affects where it can be used and what it can dial, so it should be chosen per user, not per company. (IMDA)
