The creation of virtual phone lines between your PBX and the public network is accomplished by a new technology called SIP.(Session Initiation Protocol).The following article attempts to answer the question :-Is SIP a cost effective solution to ISDN?
Using your internet connection to make telephone calls means instant savings in addition to the analogue and ISDN line rentals.
Outgoing calls will be re-routed via a box over your internet connection using the SIP trunks.Incoming calls will still go over the ISDN lines.If the internet connection goes down outgoing calls will go over the remaining ISDN lines.This allows for a risk free way to try the new technology.In essence there are no investment costs either as the savings are immediate.
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.
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 reduced call costs are an additional automatic benefit it is essential when looking for a company that offers SIP that you get a quote for these rates.
