i requested to apllay this case .
when some one call you and you already have a call , the system appear to the second caller busy tone and indecate you that there is another phone call.
can you help me
Sorry, I guess I didn't explain this too well
I understand what you are trying to achieve.....but it is not
possible. You either get a Busy signal by using Busy Trigger 1
or Ringback using Busy trigger 2. You cannot have it both ways
You don't mention what you have so I'll assume it's CUCM, You also don't mention the phone model.
You configure the maximum number of calls and busy trigger under DN config, the call busy trigger + 1 gets the CFB behavior.
If you mean you want to play a message to the user explaining the phone is in use, that's not possible.
If this helps, please rate
