CME FXO Usual tone disconnect

Question

Hi there,
I have an install of a CME with FXO ports going live this week and I was wondering if someone could check over my sound extract and confirm for me that the frequency is 415 and cadence is 510 280. I can't test until the lines go over but just want to make sure as best as I can that it will be a smooth changeover.
Also here is my cptone and voice port config:
voice class dualtone-detect-params 1
 freq-max-deviation 30
 cadence-variation 20
voice class custom-cptone DISCONNECT_CP
dualtone disconnect
frequency 415
cadence 510 280
voice-port 0/1/0
 trunk-group PSTN_TRUNKS 1
 supervisory disconnect dualtone mid-call
 supervisory answer dualtone
 supervisory custom-cptone DISCONNECT_CP
 supervisory dualtone-detect-params 1
 cptone FR
 connection plar opx 100
 caller-id enable
Thanks
Carl

Hello Carl,
The parameters are correct but the sum of cadences must be greater than "timeout wait-release" under the voice-port. You can check the timer with the command "show voice port 0/1/0".
eg   if the timer is 1 sec , 510+280=790ms < 1s , hence change the cadence value to '510 280 510 280".
