dispatcher & failover
by Jean Cérien 31 May '17

31 May '17

Hello I am working with Kamailio 5.0 dispatcher module. I am aiming at having two or more gateways receiving the traffic with load balancing, and when one fails, that the traffic is distributed among others. Currently, testing with 2 gw. I see the options message going out (and not being answered). When I monitor with kamctl dispatcher dump, I never see the faulty gw going inactive (flags remain AP), and calls are still tried to the faulty gw. "Best" result so far is with ds_probing_mode=1, the flags start at AX with both gateway up, then AP once they've replied to an OPTIONS, and even if I stop one, and OPTIONS is no longer replied, it stays at AP. when a call comes through, it is tried on this GW (3 invites), and then fails onto the other one. I was expecting that the gw would not be tried if inactive. Am I missing something ? J. modparam("dispatcher", "db_url", DBURL) modparam("dispatcher", "table_name", "dispatcher") modparam("dispatcher", "flags", 2) modparam("dispatcher", "dst_avp", "$avp(AVP_DST)") modparam("dispatcher", "grp_avp", "$avp(AVP_GRP)") modparam("dispatcher", "cnt_avp", "$avp(AVP_CNT)") modparam("dispatcher", "sock_avp", "$avp(AVP_SOCK)") modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_ping_from", "sip:probe@probe") modparam("dispatcher", "ds_ping_reply_codes", "class=2;class=3;class=4;class=5") modparam("dispatcher", "ds_ping_interval", 30) modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_probing_threshold", 3) modparam("dispatcher", "ds_timer_mode", 1)

How to get modified SDP by RTPProxy
by Albert Petit 31 May '17

31 May '17

Hi list, We are using RTPProxy as media proxy. When doing a SIPcall we would need to know the final ports used by RTPProxy. Hence I would need to access the rewritten SDP of the 200 OK send by our application server. Unfortunately we are not achieving to get that rewritten SDP. I tried calling sdp_print("1") using module sdpops just after calling rtpproxy_offer or rtpproxy_answer in kamailio script. (According the doc those methods do: "Rewrites SDP body to ensure that media is passed through an RTP proxy. To be invoked on INVITE for the cases the SDPs are in INVITE and 200 OK and on 200 OK when SDPs are in 200 OK and ACK".) However the sdp we print just after calling that is still having the original ports set by the AS but not the ports used in the rtpproxy or that we will send to the client in the rewritten SDP What are we doing wrong? Any hint how we can get the rewritten SDP in the 200 OK answer we send to caller side?

Should a proxy change Contact or From domains?
by Phil Lavin 31 May '17

31 May '17

Hi all, Theoretical question about the role of a Kamailio proxy which is also a registration server for UAs. Assuming a B2BUA on IP 1.2.3.4 behind the Kamailio proxy. Kamailio receives an INVITE from this B2BUA with From and Contact as something like sip:4321@1.2.3.4 When Kamailio routes the INVITE to that UA, is it Kamailio’s responsibility to change the domain part of the From and/or Contact to itself (e.g. sip:4321@proxy.mytld.com)? The question has arisen from Polycom missed call “call back” behaviour. When issuing a call back from a Polycom, following a missed call, it sends the call directly to the full URI in the INVITE’s From (or maybe Contact… I’ve not fully tested yet). As such the call is sent to the B2BUA, which UAs do not have access to, and thus times out. I suspect here the answer is “no”, and the Polycom must be configured to force all outbound calls through the proxy… but thoughts welcome. Cheers Phil

Is it possible to replace Request-URI in the REGISTERs with the result of dispatcher?
by 刘鲲 31 May '17

31 May '17

Hello, I build three kamailioes, one acts as a pass-through proxy as well as load-balancing, the two registrars. The kamailio_1 decides to which registrar the REGISTER should forward by a dispatcher based on db_text. ----->kamailio_2(IP2, registrar) SoftPhone--->kamailio_1(IP1, pass-through proxy)--| | ----->kamailio_3(IP3, registrar) | dispatcher(db_text) I expect the kamailio_1 forward the REGISTERs to kamailio_2/kamailio_3, and kamailio_2/kamailio_3 respond with 200 OK. But in fact, the registrars send the REGISTER back to kamailio_1. I think the reason is that the host part of Request-URI in REGISTER from SoftPhone is IP1, and kamailio_1 does not rewrite it as a pass-through proxy, so kamailio_2/kamailio_3 will find the host in Request-URI is not mine, thus route the REGISTER back to kamailio_1 according Request-URI. The setting of SoftPhone cannot be changed, so is it possible to : 1) replace host part of Request-URI in the REGISTERs with the result of dispatcher in kamailio_1 , or 2) force kamailio_2/kamailio_3 to respond rather than forward? Thanks!

push notification
by volga629＠networklab.ca 30 May '17

30 May '17

Hello Everyone, Trying understand how push notification works based on Daniel example in 2014 Code in question: if(lua_runstring("do_push([[$hdr(X-VxTo)]], [[$tU]], [[$hdr(X-VxFrom)]], [[$fU]], [[$ci]])")<0) { send_reply("501", "No link to destination"); exit; } I understand how string should look like, but lua give this error ERROR: app_lua [app_lua_api.c:607]: app_lua_runstring(): lua loading state not initialized (call: do_push([[<null>]], [[4310]], [[<null>]], [[4311]], [[dd4cb9b2-bf21-1235-05b5-5254003e39bb]])) Is possible clarify how this part should work ? volga629
