SIP: An Alternative To ISDN?
By Martin Wacey | November 24, 2009
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?
Savings can be made on ISDN and analogue line rentals by using your internet connection to make telephone calls.
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.
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.
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 such company offering this technology is Tipicall.At the moment they are running a promotion offering free SIP trunking for life.
