[asterisk-dev] No AMI event sent on dialplan variable changes via AGI and setting CLID on dial

[Tony Howat]

Hi Asteriskers,

I've been developing a large AGI/AMI based application, and found that 
Dialplan variable changes aren't passed to AMI events, unless you monitor 
NewExten - which isn't called at all if you're doing the changes via an AGI 
app.

I propose a new VarSet event to indicate these changes - this allows my 
monitoring app (AMI events) to pick up data from my AGI based application 
through setting dialplan variables.

I've submitted this to bug.digium.com along with a diff against 1.2.9.1. 
It's simple but needs reviewing to make sure I'm using the most effective 
method.

I should have disclaimer on file, it was faxed last week.

I have two changes to the Dial application to propose :

1) Play sample option - like music on hold but will play an audio sample 
looped until the caller is connected. MOH is unsuitable in my application as 
I need to play the sample from the start for each caller (ie. it's an 
instructional message like "we're putting you through now, please wait..."

2) CLID option to force the CLID of the outbound call to a specific number. 
I have a system whereby outdials go via IAX2 to another node. I do a Dial 
IAX2/thingy etc. Thing is what I need to do is alter the CLID passed out on 
the dialled call. I can do this in the out box in the context that the IAX2 
outdial goes to, but I'd rather do it from the other side so I can get the 
outbound CLID from the XML backend my app talks to. I'd like to avoid 
changing the CLID on the originating so CDR records remain "real" - the 
outbound CLID is purely fake to get past switches which are restricted to 
accept calls from certain CLIDs for security.

Do these options sound reasonable? If there's a method of achieving the 
results I'm after without modifying asterisk I'd be interested to hear them.
