1、为acc表增加额外的字段记录主叫被叫
进入mysql，选取opensips的数据库
ALTER TABLE acc ADD from_uri VARCHAR(64) DEFAULT '' NOT NULL ;
ALTER TABLE acc ADD to_uri VARCHAR(64) DEFAULT '' NOT NULL ;
2、opensips的配置
#### ACCounting module
loadmodule "acc.so"
/* account triggers (flags) */
modparam("acc", "db_flag", 1)
modparam("acc", "db_missed_flag", 2)
modparam("acc", "cdr_flag", 1)
modparam("acc", "db_url",
"mysql://opensips:opensipsrw@localhost/opensips") # CUSTOMIZE ME
modparam("acc", "db_extra", "from_uri=$fu; to_uri=$tu")
...
if (has_totag())
{
# sequential request withing a dialog should
# take the path determined by record-routing
if (loose_route())
{
if (is_method("BYE"))
{
setflag(1); # do accounting ...
setflag(3); # ... even if the transaction fails
}
else if (is_method("INVITE"))
{
# even if in most of the cases is useless, do RR for
# re-INVITEs also, as some buggy clients do change route set
# during the dialog.
record_route();
}
if (check_route_param("nat=yes"))
{
setflag(10);
}
# route it out to whatever destination was set by loose_route()
# in $du (destination URI).
route(1);
}
...
# account only INVITEs
if (is_method("INVITE"))
{
# create dialog with timeout
if ( !create_dialog("B"))
{
send_reply("500","Internal Server Error");
exit;
}
setflag(1); # do accounting
}
