Companies are seeking a cost effective solution to ISDN.The question is therefore:- Is there an alternative? SIP (Session Iniatiation Protocol) is seen by some people as an alternative as it allows for the creation of virtual phone lines between your PBX and the public network.

Telephone calls can then be made over your internet connection with the subsequent savings being made on the ISDN and analogue line rentals.

You can try this new technology in a risk free way by using the SIP trunks for outgoing calls and the remaining ISDN lines for the incoming calls.Outgoing calls could still be routed over the ISDN channels if the Internet connection fails.Trying the technology out brings immediate savings.This means there are no upfront investment costs to consider.

The result is that you will not only benefit from cheaper calls, but you can save on ISDN and analogue line rental costs as you will no longer need all the channels.

For example in any organisation not everyone needs to make or receive calls simulataneously.Most companies will normally rent more ISDN channels then they actually need.And that means unused line rental costs.What if these unused lines could be replaced by SIP Trunks at a fraction of the cost?

In a nutshell then the benefits of trying it out are clear.Replacing surplus line rental costs can be done in an entirely risk free way.Costly analogue and ISDN lines which are not being used can be a distant thing of the past.

As mentioned previously call costs will automatically decrease.Perhaps this is also worth emphasising!! When seeking a company that offers SIP it is advisable to get a quote for these costs too.

One such company offering this technology is Tipicall.At the moment they are running a promotion offering free SIP trunking for life.
