Hi Tony. Thanks for the reply. I just started to mock it up, and realised that still has a problem. My followme table in MySQL looked like this:
+----+-----------+--------+----------+--------+------+------+---------+---------+--------+---------+---------+------------+ | id | callednum | cidnum | priority | weight | app | tech | forward | options | server | context | alt_ext | soundstep | +----+-----------+--------+----------+--------+------+------+---------+---------+--------+---------+---------+------------+ | 1 | 3254100 | | 1 | 1 | Dial | SIP | 3254101 | 10|tr | NULL | NULL | NULL | tt-weasels | | 2 | 3254100 | | 1 | 1 | Dial | SIP | 3254102 | 10|tr | NULL | NULL | NULL | tt-weasels | +----+-----------+--------+----------+--------+------+------+---------+---------+--------+---------+---------+------------+ 2 rows in set (0.03 sec) Using AGI fully, this allowed me to completely customise everything, including the application to call. Asterisk extensions.conf won't let you put a variable name in place of an application command, I don't believe. exten => 3254000,1,$VAR_APP($VAR_TECH/$VAR_FORWARD....) ... won't work. -----Original Message----- From: Tony Mountifield [mailto:[EMAIL PROTECTED] Sent: Friday, January 13, 2006 10:37 AM To: [email protected] Subject: [Asterisk-Users] Re: FastAGI Command Execution In article <[EMAIL PROTECTED]>, Douglas Garstang <[EMAIL PROTECTED]> wrote: > Tony, > > It isn't that simple.

If I understand you correctly, I don't think you need a loop, if you are prepared to accept a maximum possible length of the sequence. You could just have the AGI set a channel variable for each step in the sequence, where that channel variable can contain either a single extension to dial (e.g. SIP/2001 or Zap/g1/15152221234 or Local/[EMAIL PROTECTED]) or a set of numbers to dial together (e.g. SIP/2001&SIP/2004). You would then have a dialplan something like this: [incoming] exten => _X.,1,FastAGI(whatever|${EXTEN}) exten => _X.,2,GotoIf($[ "${NUMA}" = "" ]?notfound,1) exten => _X.,3,Dial(${NUMA}) exten => _X.,4,GotoIf($[ "${NUMB}" = "" ]?notfound,1) exten => _X.,5,Dial(${NUMB}) exten => _X.,6,GotoIf($[ "${NUMC}" = "" ]?notfound,1) exten => _X.,7,Dial(${NUMC}) exten => _X.,8,GotoIf($[ "${NUMD}" = "" ]?notfound,1) exten => _X.,9,Dial(${NUMD}) exten => _X.,10,GotoIf($[ "${NUME}" = "" ]?notfound,1) exten => _X.,11,Dial(${NUME}) exten => _X.,12,Goto(notfound,1) exten => notfound,1,Playback(im-sorry-i-cannot-locate-the-person-you-called) exten => notfound,2,Hangup So if three steps were found in the database, the AGI just sets NUMA, NUMB and NUMC. If it reaches step 8, it jumps to "notfound" because NUMD is not set. Your dialplan can have as many possible steps as you want, it's not expensive.
