[Serusers] problem with accounting to PSTN gateway

Hello ! I have problem with accounting traffic from IP to PSTN gateway My PSTN gateway is 10.10.10.254 if (uri=~"sip:58[1-2]([0-9]){3}(@(gda\.pl|10\.10\.10\.24)?)" && !(src_ip==10.10.10.254/32)) { addRecordRoute(); strip(2); if (!t_relay_to("10.10.10.254", "5060")) { sl_reply_error(); }; break; setflag(1); t_relay(); }; I don't have any information about INVITE, BYE in my logs When the connection is from IP network to IP network or from PSTN to IP network I have all information what i need. Where do I have to put addRecordRoute(); and setflag(1) in ser.conf in this case ? Greetings Andrzej Radke
