UK CallerID, TDM400P, Pattern Matching and ACD Problem

Asterisk Asterisk Support

I’m do the ‘teach yourself asterisk’ thing by running asterisk behind our PBX with a TDM400P FXO port for incoming calls so, sorry if this is a dumb question but I have already searched the forum and not found an answer.

Our PBX generates UK style CallerID and I’m trying to route calls based on that but having real difficulties.

The TDM400P seems to get the CallerID (I’m running telnet to the * manager to watch it do things) but asterisk just doesn’t seem to pattern match on it :frowning:

The bit from my extensions.conf looks like:

[incoming]
exten => s,1,Wait(1)
exten => s/.Russell.Extn39.,2,Goto(Weasels,s,1)
exten => s,2,Dial(SIP/1111,20,Trt)
exten => s,3,Voicemail,u1111
exten => s,4,Hangup
exten => s,103,Voicemail
exten => s,104,Hangup

[Weasels]
exten => s,1,Answer
exten => s,2,wait(1)
exten => s,3,Playback(tt-somethingwrong)
exten => s,4,Playback(tt-weasels)
exten => s,5,Hangup

I think that should be saying; if a call comes in from RussellExtn39* then route to [Weasels] else route to SIP/1111

However, the log from *manager shows that the call is routed before the Caller ID is known :frowning:

Here’s a snip from the manager log:

Event: Newchannel
Channel: Zap/4-1
State: Unknown (9)

CallerID:
Uniqueid: asterisk-20950-1129138345.0

Event: Newstate
Channel: Zap/4-1
State: Ring
CallerID:
Uniqueid: asterisk-20950-1129138345.0

Application: Dial

Event: Newchannel
Channel: SIP/1111-011e
State: Down
CallerID:
Uniqueid: asterisk-20950-1129138348.1

Event: Newchannel
Channel: SIP/1111-011e
State: Ringing
CallerID: “Russell-Extn39” <12>
Uniqueid: asterisk-20950-1129138348.1

:cry:

If I change the pattern match to:

exten => s/_.Russell.Extn39.,2,Goto(Weasels,s,1)

Then all Caller-ID’s get routed to [Weasels]

Here’s the manager log for such a call

Event: Newstate
Channel: Zap/4-1

Extension: s

AppData: 1

I’m sure it’s something that I’m doing wrong but I’ve read the docs, searched the forums and can’t work out what.

Can anyone help?

You need to use a GotoIf in there where you evalute on ${CALLERIDNAME} data to replace the extension that you are trying to pattern match on. Something like this:

[incoming]
exten => s,1,Wait(1)
exten => s,2,GotoIf($["${CALLERIDNAME}" = “RussellExtn39*”]?Weasels|s|1:3)
exten => s,3,Dial(SIP/1111,20,Trt)
exten => s,4,Voicemail,u1111
exten => s,5,Hangup
exten => s,103,Voicemail
exten => s,104,Hangup

More on variable usage here.

This line:

exten => s/.Russell.Extn39.,2,Goto(Weasels,s,1)

Is not invoked when a call comes in I believe, and if you watch the CLI in verbose mode you will see this.

Many Thanks, your pointer put me in the right direction.

I actually ended up with:

exten => s,3,GotoIf($["${CALLERIDNAME}" : “.*Russell.Extn39.”]?Weasels|s|1:5)

For others following down the same road, the above uses a regex hence the “.*”'s
