Automatically prepend 9 when dialing from call history

[ictc]

The reason for prepending 9 was because our old phone system was set up that way, and Elastix had the same outbound route by default, so I assumed that was the best/proper way for the system to be configured. I tried doing a bit of research on whether prepending digits for outside numbers was still something that should be done and found a thread on the 3CX forums that pointed out some of the reasons for doing that, so I was hesitant to remove the requirement.

For the time being, I'm experimenting with having our outbound route accept both phone numbers prepended with 9, as well as without the 9. This way the system accepts the numbers as the Yealink handsets will dial them from the call history screens, and our users can continue prepending outside numbers with a 9 as they always have. I'm not letting the users know about this until I'm confident it won't cause much/any trouble in the future.

Thanks for your help and suggestions.
