Hanging up active calls in Asterisk PBX

by
There are many times when we run out of free channels in your PBX while making calls or in case a phone is not placed properly the calls does not gets disconnected and is shown as busy on the PBX. So at those moments it becomes a job of Administrator to monitor these logs and accordingly hangup unwanted calls to free up the channels.

Well I had to surf a lot to find the exact command to hangup calls in the latest Free PBX so here I will show you in easy steps for how to hangup active calls on PBX.

Login to your asterisk CLI console

asterisk2*CLI> core show channels
Channel              Location             State   Application(Data)
SIP/3224-00000a19    s@macro-dial-one:42  Up      Dial(SIP/4027,15,trI)
IAX2/IAX_Trunk_to_US (None)               Up      AppDial((Outgoing Line))
SIP/4003-00000a2f    s@macro-dialout-trun Up      Dial(IAX2/IAX_Trunk_to_US/1001
SIP/4001-0000089e    s-CHANUNAVAIL@macro- Up      VoiceMail(3102@default,u"")
SIP/3117-00000102    s-NOANSWER@macro-vm: Up      VoiceMail(3106@default,u"")
SIP/4027-00000a1a    (None)               Up      AppDial((Outgoing Line))
6 active channels
4 active calls

As you can see in my case there are 4 active channels and I want to disconnect user 4003 for example.

asterisk2*CLI> channel request hangup SIP/4003-00000a2f
Requested Hangup on channel 'SIP/4003-00000a30'
-- Executing [h@macro-dialout-trunk:1] Macro("SIP/4003-00000a30", "hangupcall,") in new stack
-- Executing [s@macro-hangupcall:1] GotoIf("SIP/4003-00000a30", "1?theend") in new stack
-- Goto (macro-hangupcall,s,3)
-- Executing [s@macro-hangupcall:3] ExecIf("SIP/4003-00000a30", "0? Set(CDR(recordingfile)=)") in new stack
-- Executing [s@macro-hangupcall:4] Hangup("SIP/4003-00000a30", "") in new stack
== Spawn extension (macro-hangupcall, s, 4) exited non-zero on 'SIP/4003-00000a30' in macro hangupcall'
== Spawn extension (macro-dialout-trunk, h, 1) exited non-zero on 'SIP/4003-00000a30'
-- Hungup 'IAX2/IAX_Trunk_to_US-49'

Now user 4003 has been disconnected as you can verify below.
