hi carlos, i'm looking at the commitdiff, seems like it's just indentations http://git.sip-router.org/cgi-bin/gitweb.cgi?p=sip-router;a=commitdiff;h=d0… is there something i am missing? by the way, based on the module documentation, the only dependency is the dialog module, shouldn't it include the rtimer module? is it really required? what if i would only use CNXCC_MONEY and not CNXCC_TIME or CNXCC_CHANNEL? should i still load rtimer.so before loading cnxcc.so?

hi guys, just to close this issue, i figured the problem only affects scenarios where dlg_manage() comes before cnxcc_set_max_credits() Kelvin Chua On Mon, May 12, 2014 at 10:00 AM, Carlos Ruiz Díaz &lt;carlos.ruizdiaz(a)gmail.com&gt; wrote:
