[SR-Users] Multiple OR into a if

Thu Feb 5 11:28:34 CET 2015

Hello Daniel,

Sorry, I was thinking that I have already replied with the result of this
required test.

So, I tried with single condition. All fail (xlog with != is printed) with
Request-URI and To-URI which looks like this: 0[0-9]{9}@sip.domain.tld
<mailto:%7b9%7d at sip.domain.tld> :

        if ($rU=~"^33") {

                xlog("L_WARN","RU=33\n");

        } else {

                xlog("L_WARN","RU!=33\n");

        }

        if ($rU=~"^0033") {

                xlog("L_WARN","RU=0033\n");

        } else {

                xlog("L_WARN","RU!=0033\n");

        }

        if ($rU=~"^0[1-9]{9}") {

                xlog("L_WARN","RU=06\n");

        } else {

                xlog("L_WARN","RU!=06\n");

        }

        if ($rU=~"^\+33") {

                xlog("L_WARN","RU=+33\n");

        } else {

                xlog("L_WARN","RU!=+33\n");

        }

        if ($tu=~"^sip:33") {

                xlog("L_WARN","TU=33\n");

        } else {

                xlog("L_WARN","TU!=33\n");

        }

        if ($tu=~"^sip:0033") {

                xlog("L_WARN","TU=0033\n");

        } else {

                xlog("L_WARN","TU!=0033\n");

        }

        if ($tu=~"^sip:0[1-9]{9}") {

                xlog("L_WARN","TU=06\n");

        } else {

                xlog("L_WARN","TU!=06\n");

        }

        if ($tu=~"^sip:\+33") {

                xlog("L_WARN","TU=+33\n");

        } else {

                xlog("L_WARN","TU!=+33\n");

        }

An example of a log in reply_route:

time=[Thu Feb  5 11:11:07 2015] call id=[4Yir4nAmR7] call seq=[21] contact
header=[<sip:0612345678 at A.B.C.D:5060>] from
uri=[sip:0987654321 at sip.domain.tld] from tag=[tZ-n7k92e] request's
method=[INVITE] request's uri=[<null>] to uri=[sip:0612345678@
sip.domain.tld] to tag=[a94c095b773be1dd6e8d668a785a9c84e15e43ea] sip
message id=[1] process id=[14037] ip source=[A.B.C.D] flags=[2], TU!=06

I'm agree with you: in the case of REPLY, the Request-URI is null but To URI
should match.

Thank you in advance for your help. 

Regards,

Igor.

Hello,

I was traveling and had no time for it.

Anyhow, you compare $rU, which is request uri username -- the address in the
first line of SIP requests. In the onreply_routes the SIP reply is processed
and $rU is not a valid value.

I also asked you to see if you can break the expression into multiple IF
with a single condition to see which one fails -- ie., change from:

if (exp1 || exp2 || ...) {
}

into

if(exp1) {
}

if(exp2) {
}

...

and put log messages to see which one is true or false.

Cheers,
Daniel

Hello Daniel,

Do you had the opportunity to look at this?

I was thinking to try with () between each test?

Thank you!

The To header looks like this (in compact form):

t: < <sip:0123456789 at sip.domain.tld>
sip:0123456789 at sip.domain.tld>;tag=f15e211394273201512715012\r\n

Hello Daniel,

Just to let you, it's in MANAGE_REPLY. Is that make any difference?

Regards,

Igor.

Hello,

can you paste here the SIP message (or at least the To header and request
URI) for such case? I would like to reproduce.

Also, you can try removing components of the expression in the second IF one
by one to see where it breaks.

Cheers,
Daniel

Hello,

I'm very disappointed because of the following behaviour:

     if ($tu=~"^ <sip:0> sip:0[1-9]{9}") {

            [
]

            In that case, Kamailio returns TRUE because the instructions in
the block are executed.

        }

     if ($rU=~"^33" || $rU=~"^0033" || $rU=~"^0[1-9]{9}" || $rU=~"^\+33" ||
$tu=~"^ <sip:33> sip:33" || $tu=~"^ <sip:0033> sip:0033" || $tu=~"^ <sip:0>
sip:0[1-9]{9}" || $tu=~"^ <sip:%5C+33> sip:\+33" ) {

[
]

In that case, Kamailio should return FALSE because the instructions in the
block are not executed.

        }

Am I missed something regarding 'OR' ?

Regards,

Igor.
