Re: [SR-Users] set host as inactive and probing in dispatcher
by Uri Shacked 13 Dec '11

Hi, i tried to change the ds_probing_mode as well. it didn't do any good. i need the probing mode to be set to 1 anyway. so, any ideas? here is the cfg again: after the failure route i turn to this route "route[OSPRPLERR] { xlog("$C(rg) SCRIPT : in OSPRPLERR $ru $C(xx)\n"); if($avp(OSPRPL)!=404) { xlog("$C(rg) OSPRPL is $avp(OSPRPL)* now disable destination* $C(xx)\n"); ds_mark_dst("AP"); xlog("$C(rg) *after disabling destination* $C(xx)\n"); }" here is the log: 13(5760) ERROR: <script>: SCRIPT : in OSPRPLERR sip:36264529@10.10.21.29 13(5760) ERROR: *** cfgtrace: c=[/usr/local/etc/kamailio/kamailio.cfg] l=1264 a=17 n=if 13(5760) ERROR: *** cfgtrace: c=[/usr/local/etc/kamailio/kamailio.cfg] l=1259 a=26 n=xlog 13(5760) ERROR: <script>: OSPRPL is 408 *now disable destination *13(5760) ERROR: *** cfgtrace: c=[/usr/local/etc/kamailio/kamailio.cfg] l=1260 a=26 n=ds_mark_dst 13(5760) ERROR: *** cfgtrace: c=[/usr/local/etc/kamailio/kamailio.cfg] l=1261 a=26 n=xlog 13(5760) ERROR: <script>: *after disabling destination* now i check the dispatcher list status: kamctl fifo ds_list SET:: 47 URI:: sip:10.10.21.20 flags=AX priority=25 attrs=OSP_B4 URI:: sip:10.10.21.22 flags=AX priority=25 attrs=OSP_B3 URI:: sip:10.10.21.23 flags=AX priority=25 attrs=OSP_B2 URI:: sip:10.10.21.21 flags=AX priority=25 attrs=OSP_B1 SET:: 41 URI:: sip:10.10.21.29 flags=AX priority=25 attrs=OSP_A4 URI:: sip:10.10.21.27 flags=AX priority=25 attrs=OSP_A3 URI:: sip:10.10.21.25 flags=AX priority=25 attrs=OSP_A1 URI:: sip:10.10.21.24 flags=AX priority=25 attrs=OSP_A2

Via header branch parameter in ACK message not unique
by Phillman25 Kyriacou 12 Dec '11

12 Dec '11

Dear List I'm currently facing an issue with a carrier whereby they are complaining that the via header branch parameter (sip.Via.branch == "z9hG4bKcydzigwkX") in the ACK messages is not unique which results in some calls being successful and some terminating after 20 seconds as their sip proxy determines it as a duplicate request. Is there a way to make the via header branch parameter in the ACK message unique across every transaction? Thanking you in advance for your assistance. Phillip

503 on DB Error
by Spencer Thomason 12 Dec '11

12 Dec '11

Hello all, Is it possible to configure Kamailio to reply to a request with a 503 if it cannot connect to a necessary database for the operation? I.e. Kamailio cannot connect to the database, when a REGISTER comes in and userloc can't find the credentials (due to DB failure), respond with a 503. The requesting endpoint can then fail over properly. The same behaviour would be desired for other modules as well, i.e. aliasdb. I noticed using 3.1.5 that it simply does not authorize the user. Thanks, Spencer

TLS<-->UDP not working with record_route_preset
by Gnaneshwar Gatla 09 Dec '11

09 Dec '11

Hello All, I have setup the Kamailio 3.1.0 behind a NAT/firewall. I'm using record_route_preset() function to keep the Public IP(advertised_address) in the Route header. I have to setup a where TLS->UDP and UDP->TLS to work. The sip clients do TLS and we have third party sip clients that only do UDP. The problem, Kamailio does not do double record-route when I provide record_route_preset(). This is leading to a problem where the call is either hung on TLS or UDP. I'm unsure how to go around this problem. I had posted earlier about this problem, is there a way I could use the advertised_address in the record route headers in this case? Regards Gnani

set host as inactive and probing in dispatcher
by Uri Shacked 09 Dec '11

09 Dec '11

hi, i use "ds_select_domain()" to route a call. if the destination reply with an error i am using the next lines in a route that i called from the failure route: if($avp(OSPRPL)!=404) { ds_mark_dst("IP"); } after trying this line i do "kamctl fifo ds_list" and i see the host is still at "AX". and in the next call the dispatcher still tries the same destination. why? how do i set a destinatio in dispatcher to be inactive? this is my modparams: #!ifdef WITH_DISPATCHER #------ dispatcher params --------- modparam("dispatcher", "db_url", DBURL) modparam("dispatcher", "dst_avp", "$avp(dsdst)") modparam("dispatcher", "cnt_avp", "$avp(dscnt)") modparam("dispatcher", "grp_avp", "$avp(dsgrp)") modparam("dispatcher", "attrs_avp", "$avp(dsattrs)") modparam("dispatcher", "ds_ping_from", "sip:user@host.com") modparam("dispatcher", "ds_ping_reply_codes", "class=2;code=405") modparam("dispatcher", "ds_ping_interval", 30) modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_hash_size", 8) modparam("dispatcher", "flags", 2) #!endif

unset host domain in dispatcher module
by Uri Shacked 09 Dec '11

09 Dec '11

Hi, i am using the dispatcher module in order to send the call to a LNP server. after the 3xx reply from the LNP server, i would like to send the invite back to the proxy that initiate the call from the beginnig. how do i do that? it seems that kamailio dispatcher sets the host domain in the Internet Protocol, and the sip request line does not change so to be short.. two questions: 1. how do i "undo" the dispatcher? 2. how do i make the dispatcher change the requst lineas well? (i am using ds_select_dst or ds_select_domain and they do the same...) the carrierroute module, do it better, but i need the dispatcher for the "keep alive" usage. ideas will be great :-) Uri
