Hi Amit

OK, the majority of our calls go out via zaptel fxo and pstn lines.
When these are all busy, calls are routed via a VOIP provider here in
the UK. All activity is recorded in our logs, and I can find no trace
of either 999 or 112 (if since been reminded that in the UK, you can now
also use 112 which is consistent with continental Europe).

I can't find a call placed at the relevant time that had these numbers,
even as mid-part of a string.

Below is the part which deals with our external calls. As you can see,
calls are routed out via zap, or VOIP (that's the gradwell bit). If
someone prefixes a call with "9" it forces it our via VOIP and if
someone dials "999" it is intercepted and sent via the zap channels. If
no zap channel is free, a call on channel 1 is ended and the number
re-dialled. This makes sure that emergency calls can always be placed
on a landline.

Any ideas would be appreciated!

Phil

HI Phil
Can u send me ur out call context config. Also tell me what
ur using with Asterisk to make out call SIp-Voip or Pstn line with Fxo
card?
also check with this command in ur Asterisk console. sip
show peers so u can get anybody from out side place such call inbehalf
of u. check who & how many user regsiter with ur Asterisk. if ur using
FXO card then also there is chance to check this.
also use Mysql for CDR table tocheck who try to call at time. so
u got any hint for this

Regards
Amit

OMG!!!

You're selecting 2 different output channels depending on the number
dialled!!!

(UK or international)...

That's ... LCR!!!

In ... Dialplan!!!

And according to a recent thread, that's like ... impossible, not
recommended, really really hard, with databases and external hardware
required, etc. (!!!)

Just an aside -

1) For clarity, could you use 'Z' here instead of '[123456789]'?

2) It does not look like you would be able to dial numbers that
start with 0[123456789] and then have subsequent zeros
(e.g. 01xx xxx 0000) - is that your intent?

Very good point, he probably wants.

Not impossible. I think the explanation was that it was ugly. And...
well... that is. Now, imagine sorting through a list of 500,000
possible dialing prefixes (something we have) instead of 3 or 4. Tell me
that would be clean and pretty without a DB lookup.

Anyone can LCR 2 routes in a dialplan, but that's hardly an effective
example of LCR.

. does not repeat the previous pattern, it simply matches one or more
of anything. _0Z. will happily match 0100000.

I had a recent run-in with the provider who provides my toll-free numbers, as
they had gotten a subpoena for the identity of the customer who ran some
toll-frees that were being used for fraudulent purposes. It turns out that
they had two number transposed prior to getting the subpoena, so not only
did they have the wrong customer, they subpoenaed the wrong provider.

Consider that if the police will not provide you records of the call, they may
have already discovered that they queried the wrong provider.

Oops! Yes, I see that now - my fault for confusing Asterisk pattern
matching with RFC3435 pattern matching. Sorry.

Right, and as soon as you add func_odbc to the mix, it becomes easy to query
such a database in the dialplan.

Unfortunately inventing a new regex syntax seems to be a favourite
pastime.

Perhaps it would be possible to allow exten => /00.*/,Dial... It might
cause problems with the ex-GF syntax. Another starting character could
mean RFC3435 pattern matching.

I've been suggesting that for about four years now (long before I ever
started working for Digium), but the core Asterisk developers tell me it
will have a very negative impact on Asterisk performance. I'd obviously
like to see it use a different character to inform the dialplan parser
that we're using a different pattern matching system, so that we can
limit the performance impact to just those extensions that require it.

But, for now, I've lived to learn to get along with the things that the
dialplan provides. Don't forget that we have two different regex
operators what we can use inside of an Asterisk dialplan expression. Smile

exten => _X.,1,GotoIf($[${EXTEN} : /#+[2-7][0-9]{3}/]?happy)

The only reason why it has a negative impact is because everything is
reparsed all the time. If the whole file was parsed ahead-of-time,
having switchable regexp syntaxes would only cost a mispredicted jump
each time.

Ahead-of-time parsing is currently impossible because of realtime dial
plans. That's not a showstopper for me personally, because I think the
current realtime dial plan support is a bad idea anyway, but obviously
there are others with different opinions. Another problem is the
ability to add extensions at runtime, but it should not be impossible
to call a parser function before inserting new extensions.
