Somebody can tell me what is the problem with my VIC card?
My cisco 2801, 2 VIC2-4FXO card, 2FastEthernet, 1 Serial.
My problem is the extension phone line that connected from PABX always busy when I connected it into my VIC2- 4FXO card, but when I check on the cisco there is no light on the VIC port that I have connected that phone line.
And If I take that phone line out of the VIC port and connect into the phone, it's working well and no busy.
Can somebody tell me what wrong with Cisco and VIC card?
Your reply are very appreciated.
