Moving from ISDN to SIP: the key steps you need to take

Step one: scoping the job

Work with your communications provider to find out what the move will look like for your business. This may be a wholesale switch in one move, a phased branch by branch transition, or even floor by floor. SIP can work alongside ISDN, so the switch needn’t be fraught with the panic of turning one system off and another on at the same time. Costing will also be included within this part of the process.

3 Reasons for Changing from ISDN to SIP

 

Cost

SIP trunking is not only less costly per channel for line rental than ISDN, but can also deliver savings on call costs, with many providers offering inclusive minutes as part of the monthly fee. SIP trunking requires less physical infrastructure, with fewer lines needed than with ISDN, in turn reducing the maintenance costs on required PBXs. This is all the more important for enterprise businesses, who are likely to have multiple offices and more lines. The bigger the business, the bigger the saving.
