At our remote sites we have cisco 2801 routers with VIC2-2FXS cards for the voice. This is plugged into a 2+8 PBX system locally with analogue phones connected.
Since we have upgraded the IOS from version c2801-advipservicesk9-mz.124-21.bin to c2801-advipservicesk9-mz.124-24.T4.bin the phones occasionally fail to clear down and the only wat to resolve is to reload the router. Anyone have any ideas?
