First I just need to clear up exactly what you mean.
Are you refering to the Missed call List / Feature, or the CallBack on Busy / No-answer feature.
I'll assume you mean Missed calls because the CallBack feature does not work with gateway calls.
You have 2 choices.
1) the user can edit dial the number to insert the 9 before placing the call. Most users accept this (after complaining for 5 minutes) and it is the easiest to implement because youdo not have to do anything.
2)You can apply a translation to all incoming calls from the gateway to prefix the incoming CLI with a 9.
2a) do it on call manager using a translation pattern, but this only works if the incoming CLI is always of a set length.
2b) on H.323 based gateways use translation patterns to modify the CLI.
The problem with option 2a is that variable length CLI causes problems and you may end up with more questions from users than it's worth. 2b only applies if you are using H.323 gateways but works every time.
Does this work on all calls? Caller ID provides the area code even for local calls. It looks like this would prepend a 9 in front of the area code, causing the local call to go out with a 9+area code+number.
How do you differentiate between a local and long distance calls? Seems you would have to have a set of rules to remove the area code and prepend a 9 for local numbers and a set to prepend a 91 to long distance numbers.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
