Hi, I am hitting bit of a wall here. - I am setting bflags for NAT, and SIPPING before save("location") however, when I do "kamctl ul show", the Cflag is 0. I also checked see if the bflags are set or not in the register routine - they are being set. What am I missing? snippets of the config files. #!define FLB_NATB 6 #!define FLB_NATSIPPING 7 modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) modparam("nathelper", "sipping_method", "INFO") modparam("nathelper", "sipping_from", "sip:pinger@50.62.1.7") # params needed for NAT traversal in other modules modparam("nathelper|registrar|usrloc", "received_avp", "$avp(RECEIVED)") modparam("usrloc", "nat_bflag", FLB_NATB) # Caller NAT detection route route[NAT] { #!ifdef WITH_NAT force_rport(); if (nat_uac_test("19")) { if (method=="REGISTER") { fix_nated_register(); } else { fix_nated_contact(); } setflag(FLT_NATS); setbflag(FLB_NATB); } #!endif return; } # Handle SIP registrations route[REGISTRAR] { if (is_method("REGISTER")) { xlog("L_ALERT", "REGISTER: From $fU, $fd To $tU, $td"); if (isflagset(FLT_NATS) || isbflagset(FLB_NATB)) { setbflag(FLB_NATB); # uncomment next line to do SIP NAT pinging setbflag(FLB_NATSIPPING); } # 7/28/11 - make sure only one contact location is active # at any given time # unregister("location", "$rU"); if (isbflagset(FLB_NATB)) { xlog("L_ALERT", "REGISTRAR: For $fU, $fd FLB_NATB set"); } if (isbflagset(FLB_NATSIPPING)) { xlog("L_ALERT", "REGISTRAR: For $fU, $fd FLB_NATSIPPING set"); } if (!save("location")) { xlog("L_ALERT", "REGISTRAR: From $fU, $fd Location could not be saved"); sl_reply_error(); } exit; } } The debug log snippets ================== Oct 1 15:58:30 siptest /usr/sbin/kamailio[19515]: ALERT: <script>: REGISTER: From p_krishna_test_com, 50.62.1.7 To p_krishna_test_com, 50.62.1.7 Oct 1 15:58:30 siptest /usr/sbin/kamailio[19515]: ALERT: <script>: REGISTRAR: For p_krishna_test_com, 50.62.1.7 FLB_NATB set Oct 1 15:58:30 siptest /usr/sbin/kamailio[19515]: ALERT: <script>: REGISTRAR: For p_krishna_test_com, 50.62.1.7 FLB_NATSIPPING set Oct 1 15:58:30 siptest /usr/sbin/kamailio[19515]: DEBUG: sl [sl.c:278]: reply in stateless mode (sl) Output of kamctl command ==================== $ sudo kamctl ul show Domain:: location table=512 records=1 max_slot=1 AOR:: p_krishna_test_com Contact:: sip:p_krishna_test_com@75.62.17.45:50073;transport=tcp;ob Q= Expires:: 287 Callid:: ad2d3a7bf39a4345861db1661576a7f3 Cseq:: 54856 User-agent:: QliqDesktop 1.0.0 (pjproject 1.10.0/win32) State:: CS_NEW Flags:: 0 Cflag:: 0 <================= Cflag is not being set.

Kamailio as dispatcher fails due to from domain on extension.

by Henrik Aagaard Sørensen

I'm using Kamailio as dispatcher to a FreeSwitch setup. Currently it "almost" work. I have 2 extensions connected to my FreeSwitch via Kamailio. However, I can only send calls one way because Kamailio seems to change the domain on the extension. One extension is registered with ID(a)sip.my-domain.com. This I can send calls to. The other extension is registered with ID@local-ip. This I cannot send calls to. Isn't it possible to have Kamailio register the extension on my FreeSwitch with @sip.my-domain.com? If I register both extension directly to my FreeSwitch everything works.

Setting avp from load_credentials

by Graham Wooden

Hi there, Just doing a quick test and this doesn¹t appear to be working. Kamailio 1.5.5-notls. Snippet of code: modparam("auth_db", "load_credentials", "username") . . . xlog("username is $avp(s:username)\n"); The result is '<null>'. Is this not available in the route{} ? Thanks, -graham

Use of $rU

by Graham Wooden

Hi there, What is pv for the equivalent of $rU for outbound? My inbound use of $rU has the correct username. All my subscribers are multi-number trunks, so on the outbound I need to associate the subscriber. This is kamailio 1.5. Thanks, -graham

Handling quota/call limits - kamailio 1.5

by Graham Wooden

Hi there, Finally getting around to introducing some call limits and starting with the inbound calls. However, I ran into an issue about how to get the "in use" count to be updated in my quota table. What is the best way to get s:in_use to update so it can be calculated? Here is my snippet of code: if (is_method("INVITE")) { avp_db_query("select quota, in_use from quota where username='$rU'","$avp(s:quota);$avp(s:in_use)"); if ($avp(s:in_use) >= $avp(s:quota)){ xlog ("DEBUG: Trunk $rU is over quota"); sl_send_reply("503","User over quota"); } . . } This opens up two more questions: How to decrease the call count when a BYE is received - maybe do a subtraction and the do a avp_db_query to update the table? And of course there is the BYE that won't be present (ie. When a call just rings and hangs up before it gets answered). Maybe ACC's missed_calls can somewhat be used to help determine? Thanks for any pointers and guidance. I am running Kamailio 1.5. Thanks, -graham
