1. case1. cell phone-PSTN(carrier)-analog line-analog phone
2. case2. cell phone-PSTN(carrier)-analog line-fxo(2811)-IP phone
when hang-up the call by cell phone, there is no disconnection delay for Case1 but 10 seconds for Case2.
Q1) what's difference between Case1 and Case2? Is the FXO operates different way than Case1?
Q2) for Case2, via debugging (debug vpm signal), I receive disconnection command 'fxols_offhook_disc' from Carrier 10 seconds later when the cell phone hang-up. can I control the disconnection timer before receive DISC from Carrier?
Thanks in advance,
