SIP (Session Initiation Protocol) is a new technology which allows for the creation of virtual phone lines between your PBX and the public network.Is SIP therefore a cost effective alternative to ISDN? The following explores this question.
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.
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.
When choosing a company to go with its important to note what rates they will charge you for calls.As mentioned previously its entirely possible to have this “hidden” benefit as well as the ISDN savings
One incentive currently offered by a company called Tipicall is free trunking for life
