[SR-Users] Unable to limit call duration with timeout_avp

[Admin]

Hi,
 I am using dialog time_avp() parameter to limit the call duration to a
configured number of seconds but unfortunately when the number is
reached, i get a warning but the call is not torn down. Here is the
output from the log file

3(3711) DEBUG: <script>: return value = 30 -----> $avp(i:10)

5(3713) WARNING: dialog [dlg_handlers.c:1426]: dlg_ontimeout(): timeout

Here is my config. file related to dialog module:

#!define DLG_FLAG 4

loadmodule "dialog.so"
modparam("dialog", "dlg_match_mode", 2)
modparam("dialog", "default_timeout", 3600) # 1 hour timeout
modparam("dialog", "db_mode", 0)
modparam("dialog", "hash_size", 2048)
modparam("dialog", "dlg_flag", DLG_FLAG)
modparam("dialog", "default_timeout", 3600) # 1 hour timeout
modparam("dialog", "timeout_avp", "$avp(i:10)")

if (is_method("INVITE")) {
	#$var(rv) = perl_exec("max_allowed_time");
	$var(rv) = 30;
	$avp(i:10) = $var(rv);
	xlog("L_DBG", "return value = $var(rv)\n");
	setflag(FLT_ACC); # do accounting
	setflag(DLG_FLAG);
}

Maybe i am missing some configuration related to the dialog module.

Any help is very much appreciated.

Thanks.
