I am using the avpops module to read from a mysql database to look for CFWD
information for the call. When a call is placed, it appears the command
avp_db_load attempts to read the file but all values come back as NULL. There
are no messages in the log and of course the call does not process correctly.
We are using a config that is exactly the same on a 4.3.4 version of kamailio
using cento 6.7, with a local version of mysql Ver 14.14 Distrib 5.1.73, that
works perfectly. When moving the code to kamailio 4.4.4 on Debian 8, Jessie,
mysql Ver 14.14 Distrib 5.5.53 the avp_db_load returns no information.
Here is the snippet of the code we are using. Since I am not used to
troubleshooting kamailio, please let me know what other information you need.
Thanks,
Kevin
Code snippet:
#!ifdef WITH_CFWD
xlog ("$TF Call to $rU made it into WITH_CFWD in route[LOCATION]
block\n");
# Call forwarding is enabled, so lets do a lookup to pull all AVP's for
possible call forwarding types/destinations
# Below line should load all AVP's into memory from DB for the username
portion of the TO: field from table usr_preferences
xlog("script should load from DB usr_preferences next");
avp_db_load("$tU","s/usr_preferences");
# This line i simple want to print to log when the avp load is complete
and what the values are (for debug purposes only and should typically be
commented out)
xlog("DB load should be complete");
xlog("SCRIPT: $TF Call Forwarding Unconditional set to
$avp(Unconditional)\n");
xlog("SCRIPT: $TF Call Forwarding NoAnswer set to $avp(NoAnswer)\n");
xlog("SCRIPT: $TF Call Forwarding Busy set to $avp(Busy)\n");
avp_print();
# Check to see if the AVP's are set and if so put them in log for
logging purposes
if(is_avp_set("$avp(Unconditional)"))
xlog("SCRIPT: $TF Call Forwarding Unconditional set to
$avp(Unconditional)\n");
if(is_avp_set("$avp(NoAnswer)"))
xlog("SCRIPT: $TF Call Forwarding NoAnswer set to $avp(NoAnswer)\n");
if(is_avp_set("$avp(Busy)"))
xlog("SCRIPT: $TF Call Forwarding Busy set to $avp(Busy)\n");
t_set_fr(16000, 15000); # set fr invite timeout to 16s and no response
at all to 15s to meet the specs for call fowarding no answer ringtime
# If Call fowarding Unconditional is set, we need to change the dialed
number and sent it off to the original users trunk from subscriber table
# Check to see if unconditional is set
if(is_avp_set("$avp(Unconditional)"))
# Shove this call into route [PSTN_CFWD] Block
route("PSTN_CFWD");
Here is the syslog for the same snippet:
