Well, you could improve it by combining the two substitutions into one:
$var(toto) = $(avp(aline){re.subst,/.*:(.*)@.*/\1/g});
Beyond that if this is something you do often you can use the dialplan module
[1] to store the regex as a rule and apply it anywhere you want. It may have
been designed for dialplan management but it is basically a database-backed
regex module that can be used for anything.

Thanks Ben,
yes I tried this:
$var(toto) = $(avp(aline){re.subst,/.*:(.*)/\1/g}); # delete a=channel:
xlog("line in the SDP body is $(var(toto){re.subst,/(.*)@.*/\1/g})\n");
xlog("line in the SDP body is $(var(toto){re.subst,/.*@(.*)/\1/g})\n");
It works like a charm, maybe there is a better way ...

Have you tried using the substitution transformation?

Subject: [OpenSIPS-Users] Extract data from AVP
Hi all,
I want to extract the channel ID from a line in SDP
(a=channel:d87c363c1b5b4f13@speechrecog)
I can extract this line, but I don't know how can I have only the ID
(d87c363c1b5b4f13)
Do you have a way for me please ?
thanks in advance
SDP example:
***********
m=application 1544 TCP/MRCPv2 1
a=setup:passive
a=connection:new
a=channel:d87c363c1b5b4f13@speechrecog
a=cmid:1
m=audio 5002 RTP/AVP 8 101
*************
My conf:
My result: "line in the SDP body is a=channel:d87c363c1b5b4f13@speechrecog"
I want only: d87c363c1b5b4f13 in specific avp
onreply_route[reply_mrcp]
{
xlog("L_INFO","$avp(startlog) In REPLY ROUTE MRCP - fu : $fu , si : $si , rs:
$rs\n");
if(has_body_part("application/sdp"))
{
if (search_body("m=application.*TCP\/MRCPv2"))
{
if(search_body("a=channel:.*")) {
$var(i)
=
0;
$var(whileflag)
=
0;
while ($var(i)
<
10
&&
$var(whileflag)
!=
1)
{
$avp(aline)
= $(rb{sdp.line,a,$var(i)});
if($avp(aline)=~"a=channel")
{
xlog("line in the SDP body is $avp(aline)\n");
$var(whileflag)
=
1;
}
$var(i)
=
$var(i)
+
1;
}
xlog("var i = $var(i)\n");
}
}
}
}
