Call bumping You can place or answer a voice call from a device that is attached to one of the POTS ports while Multilink PPP is active. The TA128 drops one of the channels automatically and uses it for voice calls. Once a voice call ends, TA128 automatically reestablishes the channel. For fully disconnecting with the central switch, there is a delay time between on-hook phone and channel reestablishment. The delay for reestablishing the channel is 10 seconds. During call bumping, the traffic for BOD is still under calculation. In other words, the add persist time is calculated from the time when the traffic is above the add threshold whether or not the phone is onhook or off-hook. However, it won't dial until the phone has been on-hook for 10 seconds. Call bumping works for both client (dialing) side and server (answering) side. However, the channel reestablishment is only effective on the client side. Related commands: ATCE0 - Disable the call bumping function. ATCE1 - Enable the call bumping function (default). 41
