Hello,

Is it possible to disable incoming caller ID for specific user extensions either through Asterisk, or through the Aastra 480i phones? We do not want users to be able to see who is calling them.

Thanks!

Set(CALLERID(num)= ) should work or Set(CALLERID(num)="")

Sorry for the ignorance, but exactly which file do I put this command into?

Thanks for the response!
