similarly for your USB hardware.

for the more venturesome install “List Hardware”:

will be more complete if not concise.

What is the Asterisk CLI that everyone asks me to enter to issue commands?[]

At the linux prompt type:

asterisk -r -vvvvvvvvvvv

You will now enter the Asterisk Command Line Interface of which you can run a series of commands to confirm the status of various parts of your system

How can I check what extensions my system is seeing?[]

Via the Asterisk CLI type the following command:

sip show peers

It should show you a similar listing as show below. From this we can see that extension 201 and 202 are registered and online, but extensions 203, 208 and 250 are not recognised.

Name/username Host Dyn Nat ACL Port Status

250 (Unspecified) D N A 0 UNKNOWN

208 (Unspecified) D N A 0 UNKNOWN

203 (Unspecified) D N A 0 UNKNOWN

202/202 D N A 5060 OK (153 ms)

201/201 D N A 5060 OK (9 ms)

5 sip peers [Monitored: 2 online,2 offline Unmonitored: 1 online, 0 offline]

If I edit /etc/asterisk/chan_dahdi.conf will the changes be immediate?[]

In many cases, No, it is safer to stop asterisk and reload dahdi then restart asterisk. The reason is that dahdi is a device driver that talks to the kernel and thus behaves at a lower level than most *.conf files.

amportal stop && service dahdi restart && amportal start

usually works to accomplished this (caveat, there will be a disruption of service when you do this)
