Currenlty I am running Cisco 2811 router with CCME 4.1 with SP services IOS 12.4.
I am facing the problem with Caller ID. My service provider is sending caller id information correctly with line reversal signal. But Fxo port does detect that line reversal signal and gives message saying that may due to cross cable. It does not recieved call id information from provider. According to Cisco documenatation to enable line reversal caller id we need to pre allocate DSP to FXO port and given the command also. But i am not able to get that command in version 12.4.
Is anybody ahs done similar configuration for caller ID.
I done "debug VPM signal all" and attached the output also.
