As leading IAX and SIP trunking providers, Gradwell have the knowledge, skill and technologies available to provide your business with a more flexible and affordable alternative to ISDN for in and outbound voice calls. Our IAX and SIP trunks use your internet connection to replace your traditional ISDN. The IAX or SIP trunk will then connect with our nationwide network, giving you access to the public switched telephone network (PSTN).
The Benefits of IAX and SIP Trunking
On top of being faster and at a lower cost to your business, there are plenty of other additional benefits you can get by choosing Gradwell’s IAX and SIP trunking services. These include:
- Reducing or eliminating ISDN line rental charges
- The fact you can enjoy affordable call tariffs for external calls
- You can bundle multiple numbers
- Free VoIP calls within the Gradwell network
- If you have an older switchboard you may need a gateway – we can supply these
