CNXCC Max Call control on Version 4.1.4 - sr-users

20 Feb 2015

Hi Guys,
Using kamailio Version 4.1.4 on Centos 6.5 I have an issue when using cnxcc to control max
call duration for all outbound calls.
In my configuration I set the following;
# -----Dialog params -----modparam("dialog", "dlg_flag",
4)modparam("cnxcc", "dlg_flag", 4)modparam("cnxcc",
"credit_check_period", 1)
Then I look to set some parameters for outbound calls;
###########Set Max Call Duration for MT Call  #############
$var(customer) = "MTPublic";$var(max_time) =
$var(MTMaxCallDuration);xlog("L_INFO","For setting Call Duration we have
ProfileID=$var(profileIDMD) and we have 
var(max_time)=$var(max_time)\n");cnxcc_set_max_time("$var(customer)",
"$var(max_time)");xlog("L_INFO","Max Call duration set to
$var(max_time) seconds\n");

Feb 20 14:20:26 voip01 /usr/sbin/kamailio[1950]: INFO: <script>: Max Call duration
set to 600 secondsFeb 20 14:20:35 voip01 /usr/sbin/kamailio[1960]: ALERT: cnxcc
[cnxcc_check.c:157]: check_calls_by_time(): [74d7c02e-33ae-1233-edba-005056a48754] call
has exhausted its time. Breaking the loopFeb 20 14:20:35 voip01 /usr/sbin/kamailio[1960]:
INFO: <script>: [74d7c02e-33ae-1233-edba-005056a48754]: call killed as Max Call
Duration ExpiredFeb 20 14:20:35 voip01 /usr/sbin/kamailio[1960]: ERROR: cnxcc
[cnxcc_mod.c:1068]: terminate_call(): Error executing dlg_end_dlg command. Return code was
[404]

Now as you can see, as soon as the Called party answers, the cnxcc module drops the call
stating that Max Call duration has expired, however it was set to 600 seconds.
If I restart kamailio this clears the issue and it works fine allowing calls to run up to
600 seconds.
Any help/comment on this would be great, is it just configuration related?
Thanks
Jon
