Two voice platforms. One team that already knows the endpoints.

OctaMonk has been deploying VoIP handsets since 2015. We combine an Australian-hosted in-house Standard PBX with a Premium 3CX platform so an ISP can choose the right operating model for each SMB customer.

Platform architecture

Standard for efficient hosted voice. Premium for the 3CX experience.

Both options are operated as a backend service for your ISP. The difference is the platform and the customer feature requirement—not who owns the relationship.

Endpoint experience

PBX knowledge is only half the job. The phone still has to work on the desk.

Our team works on the practical deployment layer: local network conditions, provisioning, SIP registration, NAT, firmware, DECT, softphones and end-user changes.

Voice operations

From new extension to full customer rollout.

OctaMonk can act as the operational voice team behind your ISP rather than simply handing you a PBX login.

✓New PBX/customer setup and number-routing design.
✓User, extension, ring-group, queue, IVR and voicemail configuration within platform capability.
✓IP handset and softphone rollout, provisioning and fault resolution.
✓Moves, adds and changes after the customer goes live.
✓Carrier/SIP escalation when the fault sits outside the endpoint or PBX.
