I&#39;m using the following in dialplan:<br><br> <font size="1"><span style="font-family: courier new,monospace;">id | dpid | pr | match_op |               match_exp                | match_len |                  subst_exp                   | repl_exp |              attrs               </span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">----+------+----+----------+----------------------------------------+-----------+----------------------------------------------+----------+----------------------------------</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">  3 |    3 |  0 |        1 | ^30\d{3}#\+?1?[2-9]\d{2}[2-9]\d{6}$    |         0 | ^(30\d{3}#)(\+?1?)([2-9]\d{2}[2-9]\d{6}$)    | \11\3    | normalize prefixed domestic</span></font><br>
<br>A R-URI goes in as 30001#12345678910<br>It comes out as 30001#<b>\1</b>12345678910<br><br>Can someone help me understand why? I&#39;d expect to be exactly what it was originally but for some reason &#39;\1&#39; is thrown in the middle...<br>
<br>Thanks,<br>Ryan<br>
