Outbound Failed Calls

[andrewgroup]

The following call captured in the log file failed twice in a row. This is the SnomOne CS410 appliance. The Carrier is Comcast with a 4 port DOCSIS IP to FXO gateway from ARRIS. 200 good calls are made in a day, but the clients only remember the ones that failed.

Can you shed light on what might cause the Unobtainable Tone Detection Errors?

That means the CS410 (PSTN side) detected a "fast-busy or reorder" tone for the number that was dialed out. A wrong number was dialed by the user or Comcast received a wrong number from the PBX.
