We are having a CCME with PRI line.
We wanted to configure the foll. feature:
1.When user A & B are on call & another user (either from internal or external caller) tries to call user A , user A should be able to hear some tone which will alert user A that there is an incoming call.
In other words we want to configure call waiting with a tone.
Is it possible to confure the same & if possible can somebody share the config template.
