The CLI command 'dahdi' disappeared

Hi all, I have next issue. When I have created a chan_dahdi.conf file and restarted Asterisk the CLI command ‘dahdi’ has disappeared. If this file not exists, the command is appearing back.

Listing of the chan_dahdi.conf file:

15 [channels] 16 language=en 17 ; include dahdi extensions defined in FreePBX 18 #include chan_dahdi_additional.conf 19 ; XTDM20B Port #1,2 plugged into PSTN 20 ; AMPLABEL:Channel %c - Button %n 21 group=1 22 usecallerid=yes 23 echocancel=yes 24 echocancelwhenbridged=no 25 channel=>1-15 26 switchtype=national 27 signaling=pri_cpe 28 context=from_pri_provider

Sorry, It`s my fall. “signaling” writing with 2 ‘l’ :smile:
