CID CLI Asterisk

To include CLI, you need to add the statement sendrpid=yes to the VoIP trunk entry in sip.conf.

In the dialplan, you can set a CLI for national numbers with Set(CALLERID(num)=31502102540) -> the number without + or 0 with the country code in front. For international numbers, you also use the country code (without + or 00).

For FreePBX, the entry in sip.conf (sendrpid=yes) automatically ensures that FreePBX can determine the CLI. Note that sip.conf is overwritten during a reload, so place it in sip_general_custom.conf. You can define a default CLI under a trunk. Under an extension, you can then define your "own" CLI. The number format remains the same.

For this, you can use the Asterisk function SetCallerPres(prohib) or Set(CALLERPRES()=prohib).
