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

Hello,
hmm, the format $avp(s:callfwd) should still work fine. I will look
deeper at it when I get a chance after returning to the office in few
days. Anyhow, try to use $avp(callfwd), it is the same as $avp(callfwd)
if you haven't defined an overlapping avp-alias.
On the other hand, I think avp_write(...) is no longer available. Now
you can use direct assignment, like:
$avp(callfwd) = $ruri;
One very useful additions (in newer versions than 1.0, otherwise being
quite old by now) is the sqlops module that allows to do all kind of sql
operations from configuration file, in many cases saving from the
complexity of using avpops db functions. See:
https://www.kamailio.org/docs/modules/stable/modules/sqlops.html#idp44901364
So you can do INSERT/UPDATE/REPLACE/... as you need from config file,
building the sql query with the variables you want.
Cheers,
Daniel

Hello group,
I know this may be hard to believe but I'm in the process of upgrading
an old, but stable, OpenSER 1.0 group of servers to Kamilio. I'm
basically going to sort of start from scratch with the database and
export my old MySQL database and write some scripts to reimport the data
using kamctl scripts since the database structure has changed
substantially since then it looks like.
I've mostly migrated the config file over fairly easily, except for
AVPops. I've got a section of config file that writes into the
usr_preferences database for call forwarding, but I seem to get the same
error anywhere I try to write to the database using AVPops. Here's the
output I get when checking the config:
0(1378) DEBUG: <core> [pvapi.c:268]: pv_cache_add(): PV cache not initialized,
doing it now
0(1378) ERROR: <core> [pvapi.c:828]: pv_parse_spec2(): error searching pvar
"avp"
0(1378) ERROR: <core> [pvapi.c:1032]: pv_parse_spec2(): wrong char [s/115] in
[$avp(s:callfwd)] at [5 (5)]
0(1378) : <core> [cfg.y:3368]: yyerror_at(): parse error in config file
/usr/local/etc/kamailio/kamailio.cfg, line 145, column 4-18: Can't get from cache:
$avp(s:callfwd)
ERROR: bad config file (1 errors)
Here's what I think are the revelant portions of the config file:
modparam("avpops", "db_url",
"mysql://user:pass@localhost/kamailio")
modparam("avpops", "avp_table", "usr_preferences")
modparam("avpops", "uuid_column", "uuid")
modparam("avpops", "username_column", "username")
modparam("avpops", "domain_column", "domain")
modparam("avpops", "attribute_column", "attribute")
modparam("avpops", "value_column", "value")
modparam("avpops", "type_column", "type")
<snip>
if (avp_db_load("$from/username",
"$avp(s:callfwd)"))
{
if(!avp_db_delete("$from/username",
"$avp(s:callfwd)/usr_preferences"))
{
sl_send_reply("500", "Server DB
error"); }
}
# avp_write("$ruri","$avp(s:callfwd)"); # Old
OpenSER 1.0 syntax...
$avp(s:callfwd) = $ruri; # New Kamailio syntax ??
avp_db_store("$from/username","$avp(s:callfwd)/usr_preferences");
t_relay();
return;
Basically I just want to write the ruri into the usr_preferences
database with an attribute of callfwd but not sure what I'm missing. I
see the error "Can't get from cache" but not sure how that pertains to
what I'm trying to do. Anyone have any ideas?
Thanks,
Brian
