Hello,
you have to use t_relay() instead of forward() -- some of the operations are done on transaction callbacks for replies. Try this way and if still troubles, let us know.
Cheers, Daniel

Kamailio and I'm having a world of trouble.
We are running Kamailio 3.2.3 on Debian Squeeze with the dispatcher module and recently enabled the dialog module. The call flow is
extremely simple.
We have two Asterisk servers to which we load balance the incoming calls to, nothing more.
Our dialog configuration is the default kamailio config, with the following additions:
modparam("dialog", "enable_stats", 1) modparam("dialog", "dlg_flag", FLD_DLG) modparam("dialog", "hash_size", 4096) modparam("dialog", "profiles_with_value", "callquota") modparam("dialog", "default_timeout", 300) modparam("dialog", "dlg_match_mode",2) modparam("dialog", "detect_spirals", 1) modparam("dialog", "db_mode", 0)
in request_route we have:
if ( method=="INVITE" ) { t_on_failure("FAIL_ONE"); ds_select_dst("1","4"); # sl_send_reply("100","Trying"); t_reply("100", "Trying");
dlg_manage(); setflag(FLT_ACC); # do accounting $var(SIZE) = 0; get_profile_size("callquota", "$rU", "$var(SIZE)"); if( $var(SIZE) >= MAX_NUMBER_OF_CALLS ){ xlog("DEBUG: Simultaneous calls limitreached
for $rU: $var(SIZE)\n"); sl_send_reply("503", "Simultaneous calls limit reached"); exit; }
set_dlg_profile("callquota","$rU"); if (get_profile_size("callquota","$var(SIZE)")) { xlog("DEBUG: there are $var(SIZE) totalcalls
for $rU\n"); }
forward();#uri:host, uri:port); exit();}
We also added a dlg_manage() in WITHINDLG
if (is_method("BYE")) { dlg_manage(); setflag(FLT_ACC); # do accounting ... setflag(FLT_ACCFAILED); # ... even if the transaction fails }
The problem is that some dialogs never get erased. Their total number always increases and their state is always 1
kamctl fifo profile_list_dlgs callquota dialog:: hash=2161:28334339 state:: 1 ref_count:: 1 timestart:: 0 timeout:: 0 In the debug logs I see these entries for the dialog module:

Is my config wrong ? Am I missing anything here ? Any advice would be much appreciated
