We have UC6.1 + Third Party Mobile Sip Devices. When my sip device (1) is off, and I try to call my sip device over another sip or sccp device (2), I see that my device is not registered and a call will be disconnected.
I should like to configure my sip device, so when my device is disconnected, a caller must receive a ring back and not a busy or something else.
Is it possible??
