Benefits of ISIP

Extend the life of existing hardware – if you can’t justify writing off your existing PBX or physical telephones, ISIP converters can simply plug into your current setup to ensure you can maximise existing hardware.

Reduced Line Rental – SIP Trunks offer savings of up to 70% compared to ISDN.

Reduced calls costs – Cost savings of up to 35% can be enjoyed with SIP. Dedicated packages can be tailor-made to your business which can include cut-price local, national, mobile and even international calls.

Enjoy enhanced inter-site communications – For businesses of more than one site, calls made from site to site using SIP Trunks are absolutely free and do not come out of any minute packages. With ISDN these calls were chargeable, another area of huge cost saving.

Be up and running in minutes – if you need to provision a new DDI, or if you’d like to make some changes to hunt groups, these can be done in a matter of minutes when utilising SIP Trunks. With ISDN, changes and requests such as this can take weeks.
