[SR-Users] Migrating from OpenSER config file question.

[Brian McCrary]

Hello,

Thanks so much for the help in pointing me in the right direction.  I 
finally had some time today to work with Kamailio a little.  I should 
have pointed out I had commented the avp_write line out in the config 
file and had attempted to convert it to the new format as you had 
suggested.  I had $avp(s:callfwd) = $ruri; instead of $avp(callfwd) = 
$ruri; but it seems both give the same error.

With that being said, thanks for pointing out the sqlops module.  It 
looks like I should be able to make it do everything I need, and then 
some.  There are some things I have been wanting to improve upon and it 
looks like this will certainly help.  There has been a lot of really 
nice things added to these new releases!  I'm going to give that a go 
and see if I can fix the error by eliminating the problem altogether. :)

Thanks,

Brian
