Invested heavily in your old PABX? Not ready to let go?

What happens when you are not ready to decommission your old traditional PABX but looking to cut costs with SIP Trunking and VoIP?

VadaXchange Appliance can be deployed to act as a Gateway between your old ISDN on Analogue lines on the old PABX and SIP Trunks or VOIP provider. The diagram on the right shows how this works. 

This will enable the cost savings without the expense of replacing all the phones and purchasing unified communications licences. When you are ready, you can turn on VadaXchange Buddy and get new phones. You can also stage the migration over a period of time.

SIP Trunks

Session Initiation Protocol (SIP) was created to enable voice connection to be established over a computer network. It has now been established as the industry standard for delivering phone lines via a data connection. A phone line that is delivered to you via a data connection using SIP protocol is called a SIP Trunk.

SIP trunks deliver outstanding savings compared to a traditional landline plus internet connection set up. When you get a SIP trunk, the supplier doesn't need to pay traditional telco for the landline service.

SIP trunks are high quality phone lines comparable in quality to business grade ISDN lines. Typically a SIP trunk provider delivers both data and voice over the data link to the business premises, controlling the quality of service end to end. The voice stays within the provider's network. Even though SIP trunks use the same Internet Protocol as other VoIP calls, SIP trunks differ from VoIP because they don't typically go over the internet.

There are many SIP Providers generating stiff competition, so you can negotiate great cost savings for your business.

Vadacom are experts in SIP Trunking integration for business - we were New Zealand's earliest SIP Trunk integrators.

What if you didn't need to outlay money to start getting the benefits?

Many of our clients choose Cloud PBX or lease an on-premise VadaXchange PBX rather than buying a PBX outright. The monthly payments are covered by the cost savings of an improved, consolidated phone system for your business.
