Call Drops - FreeSBC

My call dropped in the middle I was talking, I might hear fast busy or just dead air. Please check the following points to solve this issue;

  • Calls dropping at specific intervals (10 min, 30 minutes).

  • Call dropping within the first minute – missing ACK in Invite. Check NAT configuration.

  • Maximum Call time exceeded, many service providers set a limit on the maximum duration for any call passing through their system. Double check with your service provider.
