Hello,
I have the following transformation on the SDP Body:
$(rb{re.subst,/^(.*)m=audio ([0-9]+) RTP\/AVP ([0-9 ]+)\015\012(.*)$/\3/s})
However when I assign this to an AVP, i.e.
$avp(s:sdp-payloads) = $(rb{re.subst,/^(.*)m=audio ([0-9]+) RTP\/AVP ([0-9
]+)\015\012(.*)$/\3/s});
I receive back a NULL result / transformation "regex does not match" is what
I receive with high verbose syslog on kamailio.
HOWEVER.
When I do something like this:
xlog("L_INFO", "Payloads Available: $(rb{re.subst,/^(.*)m=audio ([0-9]+)
RTP\/AVP ([0-9 ]+)\015\012(.*)$/\3/s})");
It executes properly -- transformation regex matches and the payloads are
displayed as expected.
If anyone can provide any insight as to what I may be doing wrong it would
be greatly appreciated.
P.S. Kamailio SVN Revision # 2:5906M (1.5.2-notls).
Also I CC'ed devel list (as I do believe this may be a bug).
Thanks!

Hello,
interesting, when I troubleshooted before your previous report, I used
this piece of cfg:
xlog("==================================\n");
$var(b) =
"v=0\r\n"
"o=- 5 2 IN IP4 192.168.3.100\r\n"
"s=CounterPath Bria\r\n"
"c=IN IP4 174.37.XX.XXX\r\n"
"t=0 0\r\n"
"m=audio 64192 RTP/AVP 107 0 8 18 101\r\n"
"a=sendrecv\r\n"
"a=rtpmap:107 BV32/16000\r\n"
"a=rtpmap:18 G729/8000\r\n"
"a=fmtp:18 annexb=yes\r\n"
"a=rtpmap:101 telephone-event/8000\r\n"
"a=fmtp:101 0-15\r\n"
"a=nortpproxy:yes\r\n";
$var(c) = $(var(b){re.subst,|.*m=audio [0-9]+ RTP/AVP ([0-9 ]+).+|\1|s});
xlog("==================================: [$var(c)]\n");
And the xlog printed properly the value of $var(c) - meaning that it was
assigned the right value. I will test with avps next time I have a chance.
Cheers,
Daniel

Daniel,
I've also tried with script vars. I think it has something to do with the actual
dynamic psuedo variable $rb. Var assignment and mangling does not work for me either.
I.e. Keep everything the same except $var(test) = $rb and so on. Let me know if this
makes sense.

I tested with:

$var(b) = $rb;
$var(c) = $(rb{re.subst,|.*m=audio [0-9]+ RTP/AVP ([0-9 ]+).+|\1|s});

and everything looked fine. Could be something specific for your config

When I take your example with the modified regex it works. I wonder if
there is any association to using / as delimiter versus | and the () match
references?

hmm, might the / versus | in the way that you may need to use \\/ to
escape it -- just try and let me know if solves something. I used |
because I try to avoid escaping inside subst expressions and it works to
use any character you want (same like in sed tool - the character used
on first position is considered delimiter and has to be escaped when is
not).
