With traditional voice services such as ISDN (Integrated Services Digital Network) and PSTN (Public Switched Telephone Network) becoming a thing of the past, now is a good time to migrate your estate to SIP-enabled voice. Whether you do it gradually to manage the impact on your operations or decide to migrate everything in one go, we can help.
Session Initiation Protocol (SIP) enabled voice is a highly flexible and future-proof IP-voice service designed to maintain quality and business continuity at a significantly lower cost than traditional ISDN lines. Offering interoperability, a SIP phone system allows different devices, software and networks to communicate with each other seamlessly, enabling greater adaptability.
A SIP phone system successfully transmits voice data over the internet, enabling unified communications, greater reliability, and secure remote working. As an enabler for VoIP (Voice over Internet Protocol) services, SIP can support everything from voice calls and video conferencing to instant messaging and media distribution. This breadth of choice can vastly improve the customer experience, while enabling greater flexibility for your users.
We’ll actively review your individual sites and advise on new connectivity options as they become available, while delivering complete network adaptability that evolves as your business changes, helping your business stay at the forefront of voice innovations.

FAQs
SIP-enabled voice is an IP-voice service that is highly flexible and designed to future-proof your business’ voice solutions. It helps to maintain call quality and business continuity with a much lower price point than traditional ISDN lines.
SIP, or Session Initiation Protocol, is a protocol used to set up and disconnect VoIP calls and send multimedia messages over the internet. VoIP, or Voice over Internet Protocol, is an umbrella term for a group of technologies that enables voice to be sent over the internet. In essence, SIP describes how VoIP calls are established, maintained, and disconnected, so it’s a subprotocol that enables VoIP.
There are several reasons why businesses choose to move to SIP-enabled voice services from traditional ISDN or analogue lines, with the main one being to get ahead of the PSTN switch off coming in 2027. Other benefits of moving to SIP include:
- Greater resilience with services carried over the internet instead of physical lines
- Cost savings with predictable monthly costs
- No additional hardware investment
- No physical infrastructure to build or maintain
- Enabler for remote working with unified communications
- Greater network consolidation
- Immediate ROI
Having a multi-carrier network can benefit your business by avoiding reliance on one single carrier. At Nasstar, we work with several carrier partners to ensure there are multiple options for receiving and delivering your call traffic.
Should one carrier experience service or capacity issues, we can easily route your calls to another to avoid downtime. Another benefit of multiple carriers is that we can choose the optimal route for your needs, which is also often the most cost-effective.
Before your SIP-enabled voice service is installed, our presales team will work with you to understand your security, quality, and business continuity requirements in depth. We will then design the resilience of the solution to accurately meet those needs. Our teams can offer solutions that meet a variety of requirements, from efficient site transfers should one go down, or fully-mesh resilience over multiple sites.
