Is SIP cheaper than ISDN?

by Fraser Saunders

Generally the answer would be YES. SIP trunks are cheaper than ISDN30e and ISDN2e line rental, and call costs are lower when utilising SIP trunks, including zero cost site-to-site calls. However what is sometimes overlooked is the internet connectivity to deliver your SIP calls. As mentioned in the SIP reliability question, to try and push SIP calls across a low-end data connection could have a disastrous impact on your business.
