So,
For those of you who stuumble across this thred with very little Cisco experence wondering why call waiting does not work. well one possibility is when you activate a shared line in CCA it turns the call waiting off!
Step 1
open a command prompt, go to your start bar and in the run filed type cmd and hit enter. It is also located under start>all programs>accessories
step 2
type: telnet 10.1.1.1 assuming you are connected to the UC520
if telnet does not work it may be disabled in Windows vista and Windows 7 as it was for me
go to http://www.askstudent.com/tips/howto-install-telnet-client-and-server-in-windows-vista/
step 3
login to the UC520 the default is cisco/cisco unless you changed it in CCA
step 4
type: show run
this will pull up a very long list. Look for ephone-dn entrys. These are the telephone number routing/peramters for your phones. Look for the ephone number example 10,11,14 ect that is assigned to the phones call waiting is not working on. You can identify by username and password or MAC address write down the ephone numbers you need.
get back the UC520# symbol by pressing more all the way through the show run command you did.
step 5
type: config t
step 6
type: ephone-dn 14
assuming 14 is the affected phone, or else enter your ephone number you wrote down.
step 7
type: no huntstop channel
step 8
type: exit
step 9
type: exit
step 10:
type exit
step 11:
close the comand prompt
step 12:
pay it forward and answer one thred on this forum with an easy step-by-step direction for other "non-CCIE's" to be able to help them with some other issue.
