[asterisk-users] Dialplan loop

[James Collier]

I do something like this.  But I am using Realtime and 1.4

context1	85	1	Set	caller_num=${CALLERID(num)}
context1	85	2	SetMusicOnHold	default
context1	85	3	Playback	silence2
context1	85	4	AGI	context1.php
context1	85	5	Set	__FWCOUNT=0${FWCOUNT}
context1	85	6	Set	__FWCOUNT=$[${FWCOUNT}+1]
context1	85	7	GotoIf	$[${FWCOUNT}>10]?10
context1	85	8	Dial	SIP/ext1&SIP/ext2|30|m
context1	85	9	Hangup	
context1	85	10	Congestion

Try removing extra space characters around the "=". Very similar example
from my dialplan

exten => _2XX,n,Set(I=1)
...
exten => _2XX,n,Set(EXTR=$[${I} + 1])

Works fine. Also assigning a variable a new value based on the old value
works OK here (although not calculated, but concatenated):

exten => _2XX,n,Set(D=${D}&SIP/sip501)

I am using Asterisk 1.2 here, but I remember similar errors with stray
" " characters.
