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 over 15 years ago as it appeared obvious that true convergence was always going to happen. SIP has become the preferred service for business.
Converting to SIP is easy, let us bring modern day flexibility to voice.
Want resilient voice services?
Use our network to deliver calls and services when and how you want them.
If your customers are still using ISDN or moving from an analogue PBX, switching to an IP-based communication service is essential. Here are some benefits of SIP Trunking:
Easily add and scale down as required on demand. Add capacity without any need to install physical lines.
Fast and simple setup. Connecting new geographic locations enables you to get a business up and running quickly.
UK and international numbers ready to instantly provision and commission. Simply order via our portal.
Moving location, country, or just want to move to SIP? We realise numbers are essential to you, so a dedicated provisioning team looks after the process.
Facilitate global working. Ensure each country can make calls to the emergency services and receive a local call that’s not in an international call price bracket.
Find out that a PBX is down before your customers do. Monitoring and recovering from a number of voice issues can easily be set up on our portal.
Each time your PBX registers, we scan your system for threats. Included in the price of a SIP Trunk are two of the best methods.
If your PBX doesn't respond or register regularly we'll automatically route the call to an alternative number or PBX.
Ensure your SIP deployment is successful and the devices can ‘talk’ to one another. If not the calls will not go through.
SIP is the ideal enabler for adopting Unified Communication & Collaboration strategies, including remote and flexible working.
Use the same network for voice, data & video. Voiceflex have a strong background in converging you network.
Integrating WebRTC with your SIP Trunks enables a call via a web-enabled device to be delivered via our network as a SIP call.
