For most small Brisbane businesses, a cloud VoIP system is the most cost-effective starting point — low upfront cost, mobile app access, and easy scaling as you grow. If your internet connection is unreliable, or you need a high number of internal extensions, an on-premises PBX or hybrid system may be more appropriate. The right choice depends on your internet quality, team size, and how your staff work. A free site assessment from A&B Communications will give you a clear recommendation based on your actual setup.

Cost depends on the system type and number of users. Cloud VoIP typically runs $20–$50 per user per month with low upfront cost. An on-premises PBX for a small office (5–20 users) generally starts from $3,000–$8,000 installed, with lower ongoing fees. Data cabling, handsets and installation are quoted separately. A&B Communications provides free, itemised quotes — contact us for a cost estimate specific to your premises and team size.

PBX (Private Branch Exchange) is traditional on-site hardware that manages internal and external calls. VoIP (Voice over Internet Protocol) routes calls over the internet. Cloud phone systems are fully hosted VoIP systems managed in the cloud by a provider. Modern business phone systems often combine these in a hybrid configuration.

Yes — in most cases your existing business numbers can be ported to a VoIP system, including 1300 numbers, local geographic numbers and DDI numbers. A&B Communications manages the porting process to minimise disruption.

Cloud VoIP depends on your internet connection. If it goes down, desk phones will not work. Most providers offer failover options — automatically diverting calls to mobile numbers so incoming calls are not missed. A UPS can maintain connectivity during brief power interruptions. We discuss these options during the planning stage.

Yes. Many older PBX systems — including iPECS, Alcatel, NEC, Panasonic and Avaya — can still be repaired, reprogrammed and maintained. Common faults such as faulty line cards, no dial tone, incorrect call routing and voicemail failures can often be resolved without replacing the system. A&B Communications services most major brands regardless of who originally installed the system.

Yes. Under Australian law, communications cabling must be performed by a registered cabler (ACMA registered). A&B Communications holds the required ACMA cabling registration. Using an unregistered cabler is illegal and can void insurance.

Yes — phone system relocation is a core service. We handle data cabling at the new premises, disconnection and transport of the existing system, reconnection, reconfiguration and testing — with minimal downtime for your business.

SIP trunking replaces traditional ISDN or PSTN phone lines with internet-based calling, connecting your existing PBX to a VoIP carrier. For most businesses, switching to SIP trunks reduces monthly line rental and call costs significantly — without requiring a new phone system. A&B Communications can assess whether your current PBX supports SIP trunking and manage the transition.

A&B Communications provides end-to-end business phone system installation across Brisbane and South East Queensland. Services include site survey, structured cabling, system configuration, handset programming and staff training — all handled by local ACMA registered technicians. The company has been operating in Brisbane since 1998 and is an authorised dealer for iPECS by Ericsson-LG and Alcatel-Lucent Enterprise.
