Spitfire's SIP Trunking Compatibility

Click for more info ...


We have developed close relationships with many SIP compatible phone system manufacturers – and this understanding between your SIP Provider and your phone system is fundamental to the successful implementation of SIP Trunking.


Of course, the other key components is a suitable internet connection – designed for voice and able to both support SIP Trunking and terminate calls onto the traditional telephony networks (fixed line and mobile).


This makes Spitfire one of the few SIP Trunking providers able to offer a complete end-to-end SIP Trunking service – with our own SIP, Internet and Voice networks covering all aspects of SIP Trunking.


Connecting SIP trunks to your phone system


Spitfire have written specific, easy-to-understand guides to help you or your maintenance team connect Spitfire SIP Trunks to your phone system. However, generally speaking, you will require a competent technical person to set up a PBX to work with any SIP Trunking provider.


If you require on-site support or more in depth assistance, we can provide this on a chargeable basis either via our Support and Installation Team or via one of our accredited partners.
