[asterisk-users] Caller ID Rewrite

[David Bath]

Hi Anselm,

Thanks for the help...

I'm slightly confused as to your response.

Wouldn't that look for a /dialled/ number in the format _0<number> try
and jump to another extension 0044<number> with priority 1?

If so, that's not what I'm trying to achieve.

I have an external SIP provider, and the extension is a 6 digit number,
e.g. 123456.  When calls come in, they are always "TO:" this 6 digit
number..

Hence, the dialplan has 

exten => 123456,1,Goto(sipinternal,<myphoneextension>,1)

at the moment, all incoming calls are forwarded directly to my
deskphone.

What I'm trying to do is first mangle the incoming caller id (i.e. the
FROM: field) so that all numbers come in countrycode + number.

I've made a bit more progress... and my current diaplan entry looks like
this:

exten=>123456,1,Set(${IF(REGEX("^0[1-9][0-9]\{9\}$"
{CALLERID(number)})?CALLERID(number)=44${CALLERID(number):1})})
exten => 123456,2,Goto(sipinternal,101,1)

BUT! There's a very odd problem (and I'm sure it's my fault..) the
second callerid function is not being evaluated...

I.e if the "true" condition is met in the IF statement, the command
should distil down to 

Set(CALLERID(number)=44${CALLERID(number):1}

Which it does... but, "44${CALLERID(number):1}" appears as a string,
instead of being evaluated!

Any ideas why ??

Cheers,

Dave

I would try something like

exten => _0[1-9]X.,1,Goto(0044${EXTEN:1},1)
(All numbers beginning "null" "not-null" will be rewritten to 0044 plus
the number without the leading zero)
