Hopefully someone can point me in the right direction as I havn't had much luck so far. I'm trying to get call waiting to beep quietly in the background of the active call rather than playing the usual ringtone. I can enable / disable call waiting without any issue but I can't figure out how to change settings/actions.
Asterisk version is 1.6.2
Phones are Cisco 7962 running SIP firmware
Any comments would be much appreciated.
