The smart, reliable and cost-effective way to connect your business


SIP stands for ‘Session Initiation Protocol’.  It is a form of VoIP (Voice over Internet Protocol) used for receiving and making telephone calls via an Internet Connection. More simply, it is a way to use your internet connection for your phone calls as well as your regular data, removing the need to have physical phone lines into your business.


AVANSER SIP is a carrier level service that is owned by us, we aren’t reselling another company’s connection.  Your calls will pass through the AVANSER system, giving your organisation greater control over your calls. Not only does this improve your call tracking, but it allows you to leverage more of AVANSER’s product suite to reduce hardware cost and reliance on phone systems. By moving over to SIP you can track all inbound and outbound calls and enjoy free internal communication when calling internal extensions. 



What are the benefits of using SIP?


It’s the ultimate outbound solution

Track your outbound calls without having to go through the extra steps of using a dialler. SIP allows you to make calls straight from your handset as normal, or also make calls from your mobile and straight from your PC.

Eliminates the need for an answerpoint

With SIP your AVANSER line can become the answerpoint saving you time and money.


Speed up connection times 

AVANSER can pass calls to SIP extensions very rapidly. Every second counts when alleviating abandoned calls, SIP let’s you minimise the time your clients spend waiting.  


Limits the tracking numbers needed

A single tracking number can have as many extensions as needed.  One SIP line can service many people in your office.

Future proofs your business

Traditional telecommunications infrastructure is being phased out.  Phone lines are no longer needed as Internet services become stronger and faster, they can handle both data and calls.  Moving to SIP ensures that you have a reliable, current and supported way of conducting business.


SIP works with you!

There are no additional charges to add SIP functionality to your tracking numbers.
