Adding 9 to incoming calls

I have several linksys spa942 phones. They work great the system works great. However when you miss a call, and it shows in the display as missed calls, you cannot select the dial option because there is no 9 in front of the # does anyone no how to add this or where i would need to edit.

My office phone has the same problem and I wish somebody could configure the PBX to add 9. But with Asterisk, this is easy. Just add

before Dial() in your incoming context. However, if you have internal calls that do not require 9, you may want to restrict this to external calls only.

do i add this to extensions.conf

Yes. If you did not create extensions.conf yourself, you may want the original person to verify.
