SIP is a cost effective replacement for ISDN which connects a PBX to the PSTN network via Broadband, Fibre Broadband, EFM and Ethernet. It is a very efficient way to combine your network into one network carrying your voice and data together.
For clients that have already invested or upgraded their existing PBX, you can still take advantage of utilising SIP trunks to deliver your calls into your business and maintain your existing hardware. We can also provide a PBX maintenance service as part of your SIP service.
SIP trunks have a very quick provisioning time and you can increase and decrease them depending on your business needs and requirments. We can provide solutions that utilise SIP for costs savings but also include PSTN or ISDN failover services to increase the resilience and reliability of the service.
