Enterprise Grade SIP Trunks

SIP Trunks use Session Initiation Protocol (SIP) to deliver business grade telephone services over the internet. The technology, also known as Business VoIP or Business SIP, allows you to make and receive calls over a broadband internet connection.
 
In common terms, SIP Trunks are essentially business VoIP phone lines that can have one or multiple channels. The channels determine the number of concurrent phone calls that can be made. Multiple in dial numbers with specific area code prefixes can be allocated to a SIP Trunk. These are fully portable and not restricted to a particular phone exchange area. Existing PSTN and ISDN landline numbers can also be migrated to a Business VoIP service.

NBN Ready

SIP Trunks are NBN ready and don't require a telephone line to be connected. Business VoIP is the replacement technology for traditional phone lines, like PSTN or ISDN.

Reduce Telco Costs by 50%

SIP Trunks are the most cost effective way of delivering business phone line capability to a PBX phone system. SIP Trunks have significantly lower line rental and call costs.

Exceptionally Versatile

SIP Trunks can be deployed in a number of ways including PBX, IP Handset, a Softphone Application or a Mobile App. This makes them exceptionally versatile and able to fit almost any business requirement.

Common Deployment of SIP Trunks

SIP Trunks can be deployed in a number of ways. They can either be connected to an existing PBX system and act as a replacement for traditional telephone lines; or programmed into a VoIP Phone and used as a stand alone telephone line with its own telephone number. They can also be programmed into a Soft Phone on either a laptop or a PC, or into a mobile phone. This is especially useful when traveling overseas as the call being made back to Australia is charged at local Australian rates.

  • Can I Keep My Existing Numbers? Open or Close

    Can I Keep My Existing Numbers?

    Yes. BusinessCom has Local Number Portability (LNP) agreements with all the major carriers. The process of migrating phone numbers is called porting. Existing numbers allocated to PSTN and ISDN services can be ported to a business VoIP service. Once ported, they will no longer be attached to a specific telephone exchange. This is of great benefit to businesses that may want to change premises and keep the same number.

  • Typical Process of Changing Over PBX Phone Lines to SIP Trunks Open or Close

    Typical Process of Changing Over PBX Phone Lines to SIP Trunks

    If your existing PBX system is IP enabled, changing over the phone lines to business VoIP is easy.

    1. A SIP trunk with the required number of channels is issued with allocated DIDs (direct in-dial numbers / landline numbers). This is usually done within 24 hours of receiving the service application.
    2. PBX technician programs the SIP credentials into the PBX.
    3. Temporary diversions are set with the existing carrier. Calls to existing business numbers are routed to SIP numbers.
    4. Porting process of existing business numbers is commenced. Numbers will be migrated and allocated to the SIP trunk.
    5. Once the porting process is completed, old telephone lines are disconnected.

    Can I Use a SIP Trunk as a Fax Line?

    SIP Trunks are not recommended for use as fax lines. We recommend a Virtual Fax Service as a replacement.
    One of the most popular ways is to transfer your fax number to a Virtual Fax Service. That way you'll be able to eliminate the need to maintain a dedicated fax line and a fax machine.
