Frequently Asked Questions

I have an internet connection from another provider. Can I subscribe to the Maxis ONEBusiness Voice solution?
No, you have to be subscribed to a Maxis ONEBusiness Fibre/DIA/MPLS internet connection to be eligible for this solution.

Can I transfer or port my existing fixed line number (03, 05 etc.) to Maxis ONEBusiness Voice?
Currently, fixed numbers are not portable and cannot be transferred to ONEBusiness Voice, ONEBusiness VoiceConnect or ONEBusiness VoiceSIP lines. However, you can choose a new fixed voice line number with your state prefix (03, 05 etc.).

In which scenarios are ONEBusiness VoiceConnect and ONEBusiness VoiceSIP suitable for my company?
ONEBusiness VoiceConnect is suitable for customers who are looking to use a business grade fixed voice solution without having to purchase and maintain their own telephony system.

Can my existing business telephone number be used with Maxis ONEBusiness VoiceSIP or ONEBusiness VoiceConnect?
