[OpenSER-Users] DLG_count error

[[ACTIVENDY] NOC]

Hi,

I want to limit the simultaneous calls on my Openser server. I use this 
code to limit the calls:

.....

isten=xxx.xxx.xxx.xxx
listen=xxx.xxx.xxx.xxx.        # put your server IP address here
port=5060
children=4

dns=no
rev_dns=no
fifo="/tmp/openser_fifo"
fifo_db_url="mysql://xxxxxxxxxxxxxx

modparam("avpops","avp_table","gw_avail_port")

modparam("dialog", "enable_stats", 1)

modparam("dialog","dlg_flag",3)


.....



if (avp_check("$DLG_count", "gt/i:10")) {
             sl_send_reply("403","no more calls accepted");
             exit;
}

But I get the following error when I try to call and it doesn't  work:


8(4826) xl_get_spec_value: error - null sp->itf
8(4826) ERROR:avpops:ops_check_avp: cannot get src value

My Openser version is 1.1.1

Thanks
