Only SIP channels are capable of sending back reliable device state in-
formation, so it is highly recommended that you use only these channels
when using Local channels as queue members.
You can also use the AddQueueMember() and RemoveQueueMember() applications to add
members to and remove members from a queue, just like with any other channel.
AddQueueMember() also has the ability to set the state interface, which we defined stati-
cally in the queues.conf file. An example of how you might do this follows:
[QueueMemberLogin]
exten => 500,1,Verbose(2,Logging in device ${CHANNEL(peername)} into the support queue)
; Save the device's technology to the MemberTech channel variable
same => n,Set(MemberTech=${CHANNEL(channeltype)})
; Save the device's identifier to the MemberIdent channel variable
same => n,Set(MemberIdent=${CHANNEL(peername)})
; Build up the interface name and assign it to the Interface channel variable
same => n,Set(Interface=${MemberTech}/${MemberIdent})
; Add the member to the support queue using a Local channel. We're using the same
; format as before, separating the technology and the device indentifier with
; a hyphen and passing that information to the MemberConnector context. We then
; use the IF() function to determine if the member's technology is SIP and, if so,
; to pass back the contents of the Interface channel variable as the value to the
; state interface field of the AddQueueMember() application.
;
; *** This line should not have any line breaks
same => n,AddQueueMember(support,Local/${MemberTech}-${MemberIdent}
@MemberConnector,,,${IF($[${MemberTech} = SIP]?${Interface})})
same => n,Playback(silence/1)
; Play back either the agent-loginok or agent-incorrect file, depending on what
; the AQMSTATUS variable is set to.
same => n,Playback(${IF($[${AQMSTATUS} = ADDED]?agent-loginok:agent-incorrect)})
same => n,Hangup()
Now that we can add devices to the queue using Local channels, let’s look at how we
might control the number of calls to either non-SIP channels or devices with more than
one line on them. We can make use of the GROUP() and GROUP_COUNT() functions to track
call counts to an endpoint. We’ll modify our MemberConnector context to take this into
account:
[MemberConnector]
exten => _[A-Za-z0-9].,1,Verbose(2,Connecting ${CALLERID(all)} to Agent at ${EXTEN})
; filter out any bad characters, allowing alphanumeric characters and the hyphen
same => n,Set(QueueMember=${FILTER(A-Za-z0-9\-,${EXTEN})
