Spearline uses ISDN signaling to determine if a call has been answered or if there is a connection-related issue.
- The Spearline in-country server dials your Toll or Toll-Free contact number using SIP or standard ISDN phone lines provided by local carriers in-country (this replicates your customer’s experience).
- Using ISDN signaling, Spearline can determine if the call is answered or if there is a connection-related issue without ever reaching a live agent.
- When issues are found, Spearline alerts you and provides you with the call detail records needed to resolve the issues.
