Custom Dialing T46G

[sfrazier]

Could someone help me with setting up a custom key on a Yealink T46G phone that will dial a 10 digit number, pause ",,," Enter in a 4-digit passcode, pause ,,, and then dial a "*"

For example on my iphone I can do:

0000000000,,,2222,,,* and that works, I need to know how to set up a custom key:

custom 0000000000$Cp6$*$Tdtmf$$Cp6$1883*$Tdtmf$
I am not sure what the Cp Tdtmf does in the above example.

Thanks very much for anyone's help that can provide me a string that will do what the iphone does above.
