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.

Using your internet connection to make telephone calls means instant savings in addition to the analogue and ISDN line rentals.

The good news is that there is a risk free way to try the technology out whilst benefitting from the savings that the technology brings.All incoming calls will still go over ISDN lines as they do now.All outgoing calls will be re-routed via a box over your internet connection using SIP trunks.If your internet connection goes down the calls will go over your remaining ISDN lines.

As well as benefitting from savings on surplus analogue and ISDN line rental charges you will also save on the cost of the calls as well.This means an immediate return on any minor installation charges.

To illustrate this point not everybody needs to be on the phone all of the time.Companies tend to invest in more ISDN channels then they actually need with the resulting unnecessary line rental costs.SIP trunks cost a fraction of ISDN costs.

In essence any organisation has nothing to lose by trying this out.There is no risk as the remaining ISDN and analogue lines will serve as back up in the unlikely event of your Internet connection failing.

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.
