SBC Selection
When a customer places a call into PhoneIQ using any SIP or WebRTC device, through a combination of DNS queries or configuration settings, the closest available PhoneIQ session border controller (SBC) is selected.
Intelligent Voice Network
As the call reaches the PhoneIQ SBC, it will choose and route the request to a media server that will provide the best possible audio quality but will use any available resource to guarantee a call is completed.
Ensuring Call Connectivity
We partner with the best carriers in the industry, continually test and evaluate their performance and capabilities, and provide redundant PSTN routes to ensure every call is delivered even if one of our network partners is down.
