[asterisk-users] A quick question in terms of DAHDI channel

[Shitian Long]

Hello,


I have an Asterisk 1.8.11 installation. When I built up this Asterisk, I didn't install DAHDI channel, if I issue command 

connect*CLI> core show channeltypes 
I would have response like:
connect*CLI> core show channeltypes

But right now, I am planing to connect a PRI trunk to this Asterisk. so I put in a PRI card install dahdi-linux-complete-2.6.2 and libpri-1.4.14. Afterward, dahdi_tool is able to find PRI board, and all channels. But my question is when I try to send call to DAHDI channel in the dial plan, CLI print out a warning saying 
[Jun 13 07:48:21] WARNING[2393]: channel.c:5606 ast_request: No channel type registered for 'DAHDI'
According to my description above, it make sense, since my Asterisk does not install DAHDI channel before.
Therefore my question is in my case, it is required to re-intall whole Asterisk, or there is some other way that I just could only install DAHDI channel. 

I did some google search. but I didn't find a proper answer.

Thanks for your help.
