[Asterisk-Users] How to restrict simultaneous phone registrations

[Bryan Mahin]

If I lock the account down to one simultaneous call, this will resolve
one problem but create another. The user will only be able to place or
receive one call and not be able to conference call two or three people
at a time. Correct? I really need to be able to lock the account down so
multiple calls can be placed from an account at Location A but not the
same account at Location B at the same time.

Kind of like the old version of AOL instant messenger. If you logon in a
second location, it'll bump off the first location. You couldn't use it
in two places at once. An even better scenario would be that both
locations can be logged in but only the second location to login can
place calls. This would cause someone to have to close their phone and
re-open it to place calls (bumping off the other phone).

Exactly, I'll post a sample dialplan.  This dialplan is for ASTPP but
should give you the idea.
# exten => _1XXXXXXXXXX,1,Set(GROUP()=${ACCOUNTCODE})
# exten =>
_1XXXXXXXXXX,2,AGI(astpp-authorize.agi,${ACCOUNTCODE},${EXTEN})
# exten => _1XXXXXXXXXX,3,GotoIf($["${CALLSTATUS}" = "0"]?60)  ; Checks
if account has sufficient funds
# exten => _1XXXXXXXXXX,4,GotoIf($["${CALLSTATUS}" = "1"]?70)  ; Checks
if the phone number exists
# exten => _1XXXXXXXXXX,5,GotoIf($["${CALLSTATUS}" = "2"]?80)  ; Check
if account exists
# exten => _1XXXXXXXXXX,6,GotoIf($["${GROUP_COUNT()}" >
"${MAXCHANNELS}"]?90) ; Verify number of outgoing channels
#
      ; assigned to account.
# exten => _1XXXXXXXXXX,7,Set(GROUP(${TRUNK1}-OUTBOUND)=OUTBOUND)
# exten =>
_1XXXXXXXXXX,8,GotoIf($["${GROUP_COUNT(OUTBOUND@${TRUNK1}-OUTBOUND)}" >
"${TRUNK1_MAXCHANNELS}"]?10)
# exten => _1XXXXXXXXXX,9,Dial(${LCRSTRING1}||${TIMELIMIT}|${OPTIONS})
# exten => _1XXXXXXXXXX,110,Busy
# exten => _1XXXXXXXXXX,10,Set(GROUP(${TRUNK2}-OUTBOUND)=OUTBOUND)
# exten =>
_1XXXXXXXXXX,11,GotoIf($["${GROUP_COUNT(OUTBOUND@${TRUNK2}-OUTBOUND)}" >
"${TRUNK2_MAXCHANNELS}"]?13)
# exten => _1XXXXXXXXXX,12,Dial(${LCRSTRING2}||${TIMELIMIT}|${OPTIONS})
# exten => _1XXXXXXXXXX,113,Busy
# exten => _1XXXXXXXXXX,13,Set(GROUP(${TRUNK2}-OUTBOUND)=OUTBOUND)
# exten =>
_1XXXXXXXXXX,14,GotoIf($["${GROUP_COUNT(OUTBOUND@${TRUNK3}-OUTBOUND)}" >
"${TRUNK3_MAXCHANNELS}"]?16)
# exten => _1XXXXXXXXXX,15,Dial(${LCRSTRING3}||${TIMELIMIT}|${OPTIONS})
# exten => _1XXXXXXXXXX,116,Busy
# exten => _1XXXXXXXXXX,16,Set(GROUP(${TRUNK4}-OUTBOUND)=OUTBOUND)
# exten =>
_1XXXXXXXXXX,17,GotoIf($["${GROUP_COUNT(OUTBOUND@${TRUNK4}-OUTBOUND)}" >
"${TRUNK4_MAXCHANNELS}"]?19)
# exten => _1XXXXXXXXXX,18,Dial(${LCRSTRING4}||${TIMELIMIT}|${OPTIONS})
# exten => _1XXXXXXXXXX,119,Busy
# exten => _1XXXXXXXXXX,19,Set(GROUP(${TRUNK5}-OUTBOUND)=OUTBOUND)
# exten =>
_1XXXXXXXXXX,20,GotoIf($["${GROUP_COUNT(OUTBOUND@${TRUNK5})-OUTBOUND}" >
"${TRUNK5_MAXCHANNELS}"]?22)
# exten => _1XXXXXXXXXX,21,Dial(${LCRSTRING5}||${TIMELIMIT}|${OPTIONS})
# exten => _1XXXXXXXXXX,122,Busy
# exten => _1XXXXXXXXXX,22,Goto(100)
# exten => _1XXXXXXXXXX,60,Congestion ; '0' Tells them they do not have
enough money
# exten => _1XXXXXXXXXX,61,Hangup
# exten => _1XXXXXXXXXX,70,Congestion '1' Bad Phone Number
# exten => _1XXXXXXXXXX,71,Hangup
# exten => _1XXXXXXXXXX,80,Congestion
# exten => _1XXXXXXXXXX,81,Hangup
# exten => _1XXXXXXXXXX,90,Congestion    ; Their outgoing channel limit
is full already
# exten => _1XXXXXXXXXX,91,Hangup
# exten => _1XXXXXXXXXX,100,Congestion    ; No Route Available
# exten => _1XXXXXXXXXX,101,Hangup

Some of the group counts are for outgoing trunks.  It's just the first
one that you need.
