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.
Why use East Sussex Networks Ltd for SIP Trunking?
Voice networks are moving to SIP. We began this move over 4 years ago as it appeared obvious that true convergence was always going to happen. SIP has become the preferred service for business.
Key Benefits
If your 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:
Increased Flexibility
Easily add and scale down as required on demand. Add capacity without any need to install physical lines.
Rapid Deployment
Fast and simple setup. Connecting new geographic locations enables you to get a business up and running quickly.
UK & International Numbers
UK and international numbers ready to instantly provision and commission. Simply order via our portal.
Number Porting
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.
International SIP Breakout
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.
Resilience
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.
Choosing the Right SIP Provider
Not all SIP providers are the same – we believe in adding value to the SIP trunks by the way of reliability; network topology; fraud prevention; CLI presentation; call recording; number porting & provisioning and UC&C. In this very competitive market, it’s the added value which enables us to deliver high-quality working solutions.
