Hi Vivek,

Below is an example that appears to solve your problem.

Note that the regular expression in the avp_subst() statement was made 
specifically for this example.    Based on your example, the "needle" 
that is being matched is preceded by an underscore.  If this can ALWAYS 
be guaranteed then you shouldn't have a problem using this regular 
expression.  If the haystack has some other known pattern that a regular 
expression can be used to match, then all you have to do is create 
another regular expression and drop it into the example below.

  avp_write("7267261000", "$avp(s:needle)");
  avp_write("<sip:termdoneatscsf_7267261000 at test.com;lr>", 
"$avp(s:haystack)");
  avp_subst("$avp(s:haystack)/$avp(s:match)","/<sip:.*_(.*)@(.*)>/\1/");
 
  xlog("L_NOTICE", "needle=($avp(s:needle)) haystack=($avp(s:haystack)) 
match=($avp(s:match))\n");

  if (avp_check("$avp(s:needle)","eq/$avp(s:match)/g")) {
    xlog("L_NOTICE", "Match found\n");
  } else {
    xlog("L_NOTICE", "Match not found\n");
  }

Regards,
Norm
