I am trying to detect an inbound call. [globals] CELLNUMBER=1234567890 With: exten =\> 1,1,GotoIf($[${CALLERIDNUM} = ${CELLNUMBER}]?IVR,1) I get: warning[17456]: ast\_expr.y: 483 ast\_yyerror(): syntax error; Input: = 1234567890 ^^^^^^^^^^^^^^ ^ (the arrow is under the 9) [IVR] (ivr menu) if I put in the number directly in quotes or without quotes it just does nothing. Is there a way to view the debug to see what specifically it is doing? Thanks ---

i see the problem. CALLERIDNUM is null, so there is no left operand. try something like this instead: exten =\> 1,1,GotoIf($[X${CALLERIDNUM} = X${CELLNUMBER}]?IVR,1) ---

well, my Sipura phone shows the entry when it rings through. So, is it not being set before the ringing starts? ---

dunno, but the error text showing nothing before the ‘=’ is a giveaway, i’d think. have you tried my fix? ---

For some reason, now it is not pulling callerid for any callers - will se why and continue - thanks ---

I put in the entry and I get the following on the CLI: error[17965]: pbx.c:1163 ast\_func\_read: Function Callerid not registered so, it leads me to ask: CALLERID(num) looks like a function call - is it a built in? ---

that is to set the outbound caller id - i believe. I am attempting to do inbound. Now, the SIP Phone (Sipura 841) shows the callerid, but it isn’t catching it with the X$ entries ---

This is how I doit on 1.09 I am just checking the arecode and routing by it. Once it jumps to the dish270 or dish 731 then I check the NXX and route accordingly. you could easily do arecode nxx and number in 1 context but I am routing to three store based on the area code and nxx so this was the only way I coukld figure out to make it work. I would suggest making another conext with a dial dunction and your cell number and jump to it exten =\> s,1,NoOP(${CALLERID}) exten =\> s,2,GotoIf($["${CALLERIDNUM:0:3}" = “270”]?dish270,s,1:3) exten =\> s,3,GotoIf($["${CALLERIDNUM:0:3}" = “731”]?dish731,s,1:4) exten =\> s,4,Goto(ucdish,s,1) ---

Maybe it is a way that BE differs from other versions?
