[Users] Comparable regex function in openser

[CARTWRIGHT, CORY C (ATTSNET)]

Hello all,

I am attempting to add a line to the SDP of a reply using subst.

In perl I can do it like this.
	$test1 =~ s/(.+)\sRTP\/AVP\s18\s(.+)/$1 RTP\/AVP 18
$2\na=fmtp:18 annexb=no\n/g;
This ensures I have the whole "m=audio 28104 RTP/AVP 18 101 19" string
in the replacement

I started with this:
	subst('/(.*) RTP\/AVP 18 (.*)/\1 RTP\/AVP 18 \2\r\na=fmtp:18
annexb=no\r\n/g');  
As most of you probably can see this does not work.  

Does anyone know if this is possible?

Thanks.
