[OpenSIPS-Users] my problems getting dialplan to work

You know, first time I used the "fantastic" dialplan module it didn't work..
When I went back and did a select * from dialplan, I noticed that what was
IN the table wasn't anything like what I put into the table.
Seems that because of all the crazy PCRE symbols, there was quite a bit of
escaping that needed to be done for it to get into the table properly. So,
try that.. check the actual contents in the table and see if it's what is
expected..
