I have a mc3810 with IOS release MC3810-A2JSV5-M), Version 12.0(7)XK3. I’m connected directly to the PSTN through the FXO port and 4 sets (analog) connected to the FXS ports. When on a call from the PSTN and a second call is presented on the line, if I answer it (using the flash button) I disconnect the first and second call (presented with dial-tone).
The codec configured on all interface is g7ullaw. Help!!!
Thnx
