SpyChan 用於第三者監聽兩方的通話，一般多用於 Call Center 系統。

範例一：

Manager Channel
Agent Channel
Client Channel

Listen: Monitor an agents call. The manager can hear both the agent and client channels, but no-one can hear the manager.

Whisper: Whisper to the agent. The manager can hear both the agent and client channels, and the agent can also hear the manager, but the client can only hear the agent, hence “whisper.”

Barge: Barge in on both channels. The manager channel is joined onto the agent and client channels, and all parties can hear each other. Be warned, if the original agent leaves the call, the call is dropped. This is not a 3-way call.
(However you can barge in, and when comfortable, initiate a 3way call to your extension so you can continue the call without the agent. This procedure varies from client to client (soft/hard phones))

exten => _*223x.#,n,ChanSpy(sip/${EXTEN:4},qw)
exten => _*223x.#,n,Hangup

;barge
exten => _*224x.#,1,Macro(user-callerid,)
exten => _*224x.#,n,Answer
exten => _*224x.#,n,NoCDR
exten => _*224x.#,n,Wait(1)
exten => _*224x.#,n,ChanSpy(SIP/${EXTEN:4},qB)
exten => _*224x.#,n,Hangup

範例二：

設計一個 feature code 779 & 778 ，用於啟動/關閉分機的監聽功能。

[app-chanspy]
;include => app-chanspy-custom
;exten => 779,1,Authenticate(1234)
;exten => 779,n,Read(SPYNUM,extension)
;exten => 779,n,ChanSpy(SIP/${SPYNUM},q)
exten => 779,1,Authenticate(4567)
exten => 779,n,Goto(chanspy-ext,s,1)
; end of [app-chanspy]

[app-chanspy]
;include => app-chanspy-custom
exten => 778,1,Authenticate(4544)
exten => 778,n,Macro(user-callerid,)
exten => 778,n,Answer
exten => 778,n,Wait(1)
exten => 778,n,ChanSpy()
exten => 778,n,Hangup
; end of [app-chanspy]

[chanspy-ext]
exten => s,1,Background(extension)
exten => s,n,WaitExten(5)
exten => i,1,Playback(invalid)
exten => i,2,Goto(s,1)
exten => t,1,Playback(invalid)
exten => t,2,Goto(s,1)
exten => 111,1,ChanSpy(SIP/${EXTEN})

SPYGROUP 的運用

方式一：

7791 -> 分機開啟被監聽功能
7792 -> 分機關閉被監聽功能

[ext-local-custom]
exten => s,1,Set(GROUP=${DB(spygrp/${CALLERID(number)}))
exten => s,n,GotoIf($[${ISNULL(${GROUP})}]?:continue)
exten => s,n,NoOp(SPYGROUP is <${GROUP}> for ext.${CALLERID})
exten => s,n,Set(SPYGROUP=${GROUP})
exten => s,n(continue),NoOP(Ignore SPYGROUP...)

[app-chanspy-set-on]
exten => 7791,1,Answer
exten => 7791,n,Wait(1)
exten => 7791,n,Macro(user-callerid,)
exten => 7791,n,Set(DB(spygrp/${AMPUSER})=spyon)
exten => 7791,n,Playback(activated)
exten => 7791,n,Hangup

[app-chanspy-set-off]
exten => 7792,1,Answer
exten => 7792,n,Wait(1)
exten => 7792,n,Macro(user-callerid,)
exten => 7792,n,DBDel(spygrp/${AMPUSER})
exten => 7792,n,Playback(de-activated)
exten => 7792,n,Hangup

方式二：

用於所有 Inbound Call，若目的分機為 110-160 時，啟用監聽功能。
注意 Set(__SPYGROUP=spygrp)，兩個底線的用法。

使用 override 方式修改 [macro-dial] 在 extensions.conf

[macro-dial]
exten => s,1,NoOp("------------ Set SPYGROUP -------------")
exten => s,n,Set(TOEXT=${ARG3})
;exten => s,n,Set(TOEXT="150")
; Spy activate to ext.110-160
;exten => s,n,GotoIf($[ $["x${LEN(${TOEXT})}"="x3"] & $["x${TOEXT:0:1}"="x1"] & $[${TOEXT:1:1}<=6] ]?spy:nospy)
exten => s,n,GotoIf($[ $["x${LEN(${TOEXT})}"="x3"] & $[${TOEXT:0:3}<=201] & $[${TOEXT:0:3}>110] ]?spy:continue)
exten => s,n(spy),Set(__SPYGROUP=spygrp)
exten => s,n(continue),NoOp("--------- Nothing --------")
exten => s,n,GotoIf($["${MOHCLASS}" = ""]?dial)
exten => s,n,SetMusicOnHold(${MOHCLASS})
exten => s,n(dial),AGI(dialparties.agi)
exten => s,n,NoOp(Returned from dialparties with no extensions to call and DIALSTATUS: ${DIALSTATUS})
