Internet Telephony Service Provision (ITSP)
As VoIP, or IP telephony, has become recognised as the de facto standard, so more data network providers are offering ITSP services. Our extensive research and testing means that we can provision the best ITSP providers, both in terms of reliability and call tariffs. The leading service offered is SIP (Session Initiation Protocol) Trunking.
SIP Trunking
The emergence of VoIP has led to a greater uptake in SIP Trunking. There are many business benefits to moving away from costly ISDN circuits to SIP Trunks. We wrote an article ‘Have you considered SIP Trunking?’, which outlines in detail these benefits.
In summary, the benefits are:
- Only paying for required capacity
- Eliminating the need for ISDN lines, therefore rental charges
- Cheaper rental charges
- Cheaper call charges
- Less hardware costs
- Increased resilience with built-in disaster recovery
- Increased connectivity capacity
Moving from ISDN to SIP Trunking could not be simpler. If you have an existing data network that has the capacity to carry voice calls and can offer QoS then it can be used. Otherwise we can provide a range of delivery networks.
