OK I know this isn’t necessarily an issue specific to FreePBX/Asterisk, but I figured I would ask it here anyway.
I have some SPA942 phones and all the CID info on inbound calls starts with a +1NPANxxXXXX. If I hit redial, the asterisk logs show that an invalid extension is being dialed. Assuminig I want to fix this on the LinkSys phone, how would I change the dial plan to strip the “+” symbol or perhaps substitute the “+” symbol for a 9? I have seen and read some posts on ways to modify the CID that comes in, though I would prefer not to do it this way.
