VOICE ASSURE INTERSTATE Proactive testing of your contact numbers
Replicate a call from one state to another to test for connectivity, audio quality and latency.
HOW DOES INTERSTATE WORK? Interstate allows you to replicate a call from one state to another state across the US and Canada.
Here's how:

Select originating and terminating states
Simply select a state, such as Texas, to originate the call from. The terminating call can be in another state, this is usually where the terminating number resides.

Server dials your number
The Spearline server dials your toll or toll-free contact number through our in-state carrier. We use SIP or standard phone lines with ISDN signaling to replicate your customers’ experience.

Test is carried out
Working with our in-state carriers, Spearline can test for connection and quality issues to your inbound numbers from as many as 20 different states across the US and Canada.
