I'm new in Cisco. I have 2811 router with VWIC-1MFT-E1 and I want to connect 2 different network to it (data & voice).
my question is :
At first I'm connect the VWIC-1MFT-E1 to Pbx. The system is working fine. But when I'm connect the 10/100 Fast Ethernet ports to Data network, the Pbx start going intermittent. Can you help me how to solve this ? Is my config is wrong ?
