WHAT IS A SIP TRUNK?
A SIP Trunk is the virtual link between your PBX and the PSTN over the internet. It allows you to make outbound calls and receive inbound calls using an IP connection (VoIP) rather than a traditional ISDN/PSTN line. With ISDN being phased out and moving to all-IP, SIP Trunks will be essential.
Voice networks are moving to SIP. We began this move years ago as it appeared obvious that true convergence was always going to happen. SIP has become the preferred service for business.
- Provide flexible and resilient voice services
- Maximise investments and leverage your IP infrastructure
- Simplify a business’s phone system operation
- Facilitate the switch from ISDN to all-IP services
Converting to SIP is easy, let us bring modern day flexibility to voice
