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!
Sincerely, Brandon Armstead
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.

Hello,
I tested with:
xlog("===============================+++: [$rb]\n"); $var(b) = $rb; $var(c) = $(rb{re.subst,|.*m=audio [0-9]+ RTP/AVP ([0-9 ]+).+|\1|s}); # $var(c) = $(var(b){re.subst,|.*m=audio [0-9]+ RTP/AVP ([0-9 ]+).+|\1|s}); xlog("===============================+++: [$rb]\n"); xlog("==================================: [$var(c)]\n");
and everything looked fine. Could be something specific for your config or environment, what is content-length of your invite?

Daniel,
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).
