Hi I have the following setup phone - mta - asterisk - patton_sn2400 - PRI I am trying to program *67 to block caller id name and number To do this correctly I have to leave the fields callerid name and number unchanged and only set the flag callerpres to restricted The problem seems to be that Asterisk replace the name and number to unknown and then send the call to my Patton box. How can I make this setup work ? Patrick
