Customer had requirements of a third party fax server, served by analog ports on a VG224, to send custom tones to the devices on the FXS side. The devices in this case were analog Dialogic board ports of some sort.
My first instinct was to create a new voice class and apply it to the voice ports like so:
voice class custom-cptone MyFax
dualtone busy
frequency 425
cadence 250 250
dualtone reorder
frequency 425
cadence 320 320
voice-port 1/1/0
supervisory custom-cptone MyFax
This not only won't work, it's not what it's for.
You need to use the "test voice tones" command. The fact that the command is test seems counter-intuitive, but it works.
First, do a "test voice tones
MyVG224#test voice tone C1 show
Code: C1 Country: Custom1
DTMF freq.(Hz) Row / col: 697, 770, 852, 941 / 1209, 1336, 1477, 1633

OFFHOOK_ALERT 4 1400 2040 -150 -150 -185 -150 -150 -185 100 100 0 0 0 0 0 0
If, for example you want to modify what dial tone sounds like when an FXS port goes off-hook, you would execute:
test voice tone C1 DIALTONE 2 340 440 -165 -165 -185 -165 -165 -185 65535 0 0 0 0 0 0 0
In this case, I am changing the first frequency in a dual tone frequency from the default 350 to 340.
You then simply apply the new settings to the voice port via
voice-port 2/0
cptone C1
You can verify the changes / new settings by simply running "test voice tone C1 show" again, and your modifications should have replaced the defaults.
This change DOES NOT show in the running-configuration and WILL NOT survive a gateway reboot.
The make them "permanent" you need to add commands to reapply the changes when a syslog "restarted" event is raised. For example, to make my change above get reapplied after a reboot, you must add the following to your running config:
event manager applet Tone-application
event syslog pattern "%SYS-5-RESTART: System restarted"
action 1.0 cli command "enable"
action 1.1 cli command "test voice tone C1 DIALTONE 2 340 440 -165 -165 -185 -165 -165 -185 65535 0 0 0 0 0 0 0"
Note here that you can make changes to any number of tones like BUSY, RING_BACK, etc. by adding additional lines to the config and incrementing the action 1.X command. For example, changing both DIALTONE and BUSY on a restart, you would enter the following.
event manager applet Tone-application
event syslog pattern "%SYS-5-RESTART: System restarted"
action 1.0 cli command "enable"
action 1.1 cli command "test voice tone C1 DIALTONE 2 340 440 -165 -165 -185 -165 -165 -185 65535 0 0 0 0 0 0 0"
action 1.2 cli command "test voice tone C1 BUSY 2 500 0 -170 -170 -240 -170 -170 -240 550 550 0 0 0 0 0 0"
If you want to get crazy, try changing the DIALTONE and RING_BACK tones to something high like 1000 and / or changing the on / off times to something short like 100 so you're confident, just by ear, the changes are effective.
