Learn moreWhat you get
Traditional phone lines are costly and hard to scale. Cloud PBX moves the switchboard to the cloud so staff use one company line from a desk phone, mobile app or computer; SIP trunking keeps your existing system while cutting call and IDD costs.
Cloud PBX
Auto-attendant, voicemail-to-email, call routing and recording — all configured in the cloud.
SIP trunking
Keep your existing PBX, slash line rental and IDD, and scale channels on demand.
Keep your number
Port your existing landline numbers with zero interruption.
Mobile & desktop
One extension rings on desk phone, mobile app and softphone together.
Teams voice
Make and take company calls directly inside Microsoft Teams.
IDD & conferencing
Low-cost international calling and multi-party video / voice conferencing.
Fax by email, no machine needed
One virtual HK fax number with everything via email and incoming faxes as PDF. No machine, toner or fax line, and the team can share a single number.
Business mobile + broadband, one bill
Bundle the 5G corporate mobile plan with office broadband on a single vendor and bill, with pooled data and business pricing for simpler admin.
Microsoft Teams Phone
Connect company calling into Teams via Operator Connect or Direct Routing. HK has no native Calling Plan, so a local carrier provides the PSTN breakout.
