Create smarter working advantages with SIP trunking

For organisations currently connecting to voice services through ISDN circuits, there are significant benefits to migrating to SIP trunks, including:

Experience substantial cost savings with SIP trunks, as both the setup and ongoing rental costs are significantly lower than ISDN. In some cases, organisations can achieve savings of up to 70% in line rental expenses.
SIP trunks not only offer customers cheaper call charges but also eliminate the cost of internal calls, keeping them within the network. This cost-effective solution enhances overall communication affordability and efficiency.
Unlike traditional ISDN, which requires the purchase of fixed circuit increments, SIP provides the flexibility to provision the exact number of channels needed. Additionally, it offers the agility to instantly scale up or down as per your requirements.
Utilising VoIP, SIP trunks offer enhanced resilience by enabling the distribution of voice delivery across multiple physical circuits. This flexibility allows for instantaneous switching in call routing across your network.
