Is it possible to enter long distance codes in a CFwdAll from a phone?
If you are referring to FAC's (Forced Auth Codes) in CCM, these cannot be entered into the Call Forward All string :(
Calls that are forwarded to a FAC- or CMC-enabled route pattern fail because no user is present to enter the code. This limitation applies to call forwarding that is configured in Cisco CallManager Administration or the Cisco CallManager User Options Pages. You can configure call forwarding, but all calls that are forwarded to a FAC- or CMC-enabled route pattern results in reorder. When a user presses the CFwdALL softkey and enters a number that has FAC or CMC enabled on the route pattern, the user receives reorder, and call forwarding fails.
You cannot prevent the configuration of call forwarding to a FAC- or CMC-enabled route pattern; forwarded calls that use these route patterns drop because no code is entered. To minimize call-processing interruptions, test the number before you configure call forwarding. To do this, dial the intended forwarding number; if you are prompted for a code, do not configure call forwarding for that number. Advise users of this practice to reduce the number of complaints that result from forwarded calls that do not reach the intended destination.
From this good doc;
Hope this helps!
