I have two lines in my dialplan that I wish to make it into only one, and I
fail
X.,n(entrada),Set(CALLERID(num)=${CALLERID(num)}0000000000)
X.,n,Set(CALLERID(num)=${CALLERID(num):0:11})

It means: add '0000000000' to the caller id, and then take the first 11
chars from the left. It aims to detect null caller ids and replace them by
zeros. How can I write this expression in just one line?

I think it does multiple passes to evaluate ${} so maybe
Set(CALLERID(num)=${${CALLERID(num)}0000000000:0:11})
works.

However assuming a callerid to always be 11 chars is not
generally valid.

Gr??e,

First, it doesn't do what your explanation says it does.

Second, why would you want to? Any savings in execution time will be
insignificant and it will obscure the intent and "readability" of the
code.

FYI, my 2.6GHz P4 executes about 3,000 CALLERID(num) assignments per
second.

Thanks in advance,

Not in 1.2.

You could always do something like this, but I think it may pull more
proc than on 2 lines:

exten => s,n,Set(CALLERID(num)=${IF($["foo${CALLERID(num)}" = "foo"]?
0000000000:${CALLERID(num)})})

For some reason, your post reminded me of how to do it:

Set(CALLERID(num)=${SPRINTF(%010lld,0${CALLERID(num)})})

This should do it, but I've not actually tested it. It is based on a
line from my own dialplan.

_X.,n(entrada),Set(CALLERID(num)=${IF($[${LEN(${CALLERID(num)})} =
0]?0000000000:${CALLERID(num):0:11})})

Believe it or not, I cannot find online a single piece of documentation for
the Asterisk function SPRINTF. This example does not work, for it changes
the caller id.
Set(CALLERID(num)=${SPRINTF(%010lld,0${CALLERID(num)})}),
For instance, if the incoming caller id is 17864335989, I get 0684466805 out
of that function, which is not intended one. To be precise, of the caller
has less than 10 chars, I want to complete it with a string of '0's. If the
caller id is nothing, or empty, I want to replace it with 10 zeroes. I guess
I can figure it out if a link to the documentation of SPRINTF is provided.

TP'n to follow flow.

I haven't seen anyone mention ISNULL so there is an example (obviously
wrap it in the below Set(CALLERID(num)=...) as the other examples are)

${IF(${ISNULL(${CALLERID(num)})}?0000000000:${CALLERID(num)})}

Well, 10 chars or 4294967296 to be precise is the limit of integer, so
on 32 bit platform this won't work. Just do the string processing Smile

Btw - some kind of str_pad function in dialplan would be nice Wink

Oddly "core show function SPRINTF" works on my 1.6. SPRINTF function
does not seem to be in 1.2 and I don't have any 1.4 systems.

Wasn't "googling" for "asterisk function sprintf" productive?

SPRINTF is not in 1.2

This is obtuse. Unless the guy modifying your dialplan 5 years from now is
a reasonably advanced C programmer, he will have no clue what you were
trying to accomplish.

Aside from not handling the null case correctly, your original 2 line code
was "better." Making your dialplan maintainable is more important than
potentially shaving a fraction of a millisecond off the execution time.

Thanks in advance,

core show function SPRINTF does work on my 1.4.20 system.
