[asterisk-users] ODBC dialplan looping problem

Thu Apr 18 06:15:57 CDT 2013

All,

Thank you in advance for any help.

I have a customer in need of a conferencing system.  A requirement is for
users to each have their own PIN for the same bridge.

So, I put the list of users, PINs bridges into a MYSQL DB and used an ODBC
connector to parse the table.

Asterisk is connected and reads the rows as expected.  The problem is that
if a user enters a PIN that is NOT in the table, asterisk goes crazy and
continues to loop forever.

Please have a look and tell me where I went so wrong.

Func_odbc.conf looks like this:

[PIN]

dsn=BRIDGE

mode=multirow

readsql=SELECT pin from users WHERE confid='${SQL_ESC(${CONF_ID})}'

extensions.conf section:

[infromhost] ;Host dials 8888 over SIP trunk exten=8888,1,Answer

exten=8888,n,Background(conf-getconfno)

exten=8888,n,WaitExten(10)

exten=8888,n,Hangup

exten=_XXXXXX,1,Set(GLOBAL(CONF_ID)=${EXTEN})

exten=_XXXXXX,n,GoTo(rooms,${EXTEN},1)

;

[rooms]

exten=_XXXXXX,1,Set(CONF_ID=${EXTEN})

exten=_XXXXXX,n,Background(conf-getpin)

exten=_XXXXXX,n,WaitExten(5)

exten=_XXXXXX,n,Hangup

exten=_1XXXXX,1,Goto(getpin,${EXTEN},1)

exten=_2XXXXX,1,Goto(getpin,${EXTEN},1)

exten=_3XXXXX,1,Goto(getpin,${EXTEN},1)

exten=_4XXXXX,1,Goto(getpin,${EXTEN},1)

exten=_5XXXXX,1,Goto(getpin,${EXTEN},1)

exten=_6XXXXX,1,Goto(getpin,${EXTEN},1)

exten=_7XXXXX,1,Goto(getpin,${EXTEN},1)

exten=_8XXXXX,1,Goto(getpin,${EXTEN},1)

exten=_9XXXXX,1,Goto(getpin,${EXTEN},1)

exten=i,1,Goto(getpin,${CONF_PIN},1)

;

[getpin]

exten=_XXXXXX,1,Set(GLOBAL(CONF_PIN)=${EXTEN})

exten=_XXXXXX,n,Set(ODBC_ID=${ODBC_PIN(1)})

exten=_XXXXXX,n(loop_start),NoOp()

exten=_XXXXXX,n,Set(ROW_RESULT=${ODBC_FETCH(${ODBC_ID})})

exten=_XXXXXX,n,GotoIf($["${ODBC_FETCH}" = "FAILURE"]?cleanup,1) 

exten=_XXXXXX,n,GotoIf($["${ROW_RESULT}" = "${CONF_PIN}"]?good_exten,1)

exten=_XXXXXX,n,Goto(loop_start)

;

exten=cleanup,1,Verbose(1,Finish up)

same=n,Verbose(1,PIN not found)

same=n,ODBCFinish(${ODBC_ID})

same=n,playback(conf-invalidpin)

same=n,Goto(rooms,${CONF_ID}1)

same=n,Hangup()

;

exten=good_exten,1,Verbose(1,The PIN is available)

same=n,ODBCFinish(${ODBC_ID})

same=n,Verbose(1,Drop Caller into the bridge)

same=n,Set(CONFBRIDGE(user,template)=default_user)

same=n,ConfBridge(${CONF_ID},default_bridge,,sample_user_menu)

same=n,Hangup()

;

The log shows the 3 existing DB table rows are found but continues to cycle
indefinitely if the PIN is NOT found.

First few rows of the console log:
