[4.2.8] SUBSCRIBE message was not handled

by Jack Wang

Hello everyone, According to the routing flow set in kamailio.cfg # handle retransmissions if(t_precheck_trans()) { t_check_trans(); exit; } t_check_trans(); After I traced the flow it seems that SUBSCRIBE message failed on t_check_trans() and stopped there. I add some logs to keep tracing this function and found that: int t_check_trans(struct sip_msg* msg) { struct cell* t; int branch; int ret; /* already processing a T */ if(is_route_type(FAILURE_ROUTE) || is_route_type(BRANCH_ROUTE) || is_route_type(BRANCH_FAILURE_ROUTE) || is_route_type(TM_ONREPLY_ROUTE)) { return 1; } if (msg->first_line.type==SIP_REPLY) { branch = 0; ret = (t_check_msg( msg , &branch)==1) ? 1 : -1; tm_ctx_set_branch_index(branch); return ret; } else if (msg->REQ_METHOD==METHOD_CANCEL) { return w_t_lookup_cancel(msg, 0, 0); } else { switch(t_check_msg(msg, 0)){ case -2: /* possible e2e ack */ return 1; case 1: /* found */ t=get_t(); if (msg->REQ_METHOD==METHOD_ACK){ /* ack to neg. reply or ack to local trans. => process it and end the script */ /* FIXME: there's no way to distinguish here between acks to local trans. and neg. acks */ if (unlikely(has_tran_tmcbs(t, TMCB_ACK_NEG_IN))) run_trans_callbacks(TMCB_ACK_NEG_IN, t, msg, 0, msg->REQ_METHOD); t_release_transaction(t); } else { /* is a retransmission */ if (unlikely(has_tran_tmcbs(t, TMCB_REQ_RETR_IN))) run_trans_callbacks(TMCB_REQ_RETR_IN, t, msg, 0, msg->REQ_METHOD); t_retransmit_reply(t); } /* no need for UNREF(t); set_t(0) - the end-of-script t_unref callback will take care of them */ return 0; /* exit from the script */ <---------------------------- THE POINT !! } /* not found or error */ } return -1; } If the line "return 0; /* exit from the script */" was changed to "return 1; /* exit from the script */" , it works ---- means that the configuration script can keep being proceeded now. Any suggestions?

Path module adds either received or outbound

by Rick Barenthin

Hey, Maybe someone from the list can share some information about the path module. Why can the path module only add either the received parameter to path or the flow token with the ob parameter, but not both. Does the RFC mandates it? I didn't find anything like that and was wondering because the source calculates max length of the parameters with following: >> /* maximum possible length of suffix */ >> suffix_len = strlen(";lr;received=sip::12345%3Btransport%3Dsctp;ob;>\r\n") + IP_ADDR_MAX_STR_SIZE + 2 + (add_params ? add_params->len : 0) + 1; This looks like it can be possible to have both. Best regards Rick

tsilo ts_store() causes segfault if method is not INVITE

by Anthony Alba

I was modifying the routing blocks of the tsilo push notifications recipe from Federico Cabiddu and could cause a segfault in kamailio 5.0.3 if due to misconfiguration an ACK reached ts_store(). ## modify https://www.kamailio.org/events/2015-KamailioWorld/Day2/20-Federico.Cabiddu… ## various route blocks will lead to here ## including ACK and INVITE... route[LOCALRELAY) { ## ooops: did not check method is INVITE t_relay(); ts_store(); $sht(vtp=>stored::$rU) = 1; xlog("L_INFO", "stored transaction [$T(id_index):$T(id_label)] $fU => $rU\n"); ## saw an ACK and caused segfault } If properly checked for INVITE: if (is_method("INVITE")) { /* do tsilo stuff */ } it works. I'm wondering whether ts_store() should/could be more defensive and show an error like "..not the right context for ts_store().." . Thanks for you thoughts. Anthony

kamailio with NAT IP and DNS loadbalance

by mlwu＠south-star.com.cn

Hi, Here are same problems in my configuration of kamailio server. I have two kamailio server (both have a NAT IP and a lan IP), and I use DNS to keep loadbalance.When sending message to another account , if NAT IP which is returned by DNS, is not the same as receiver account, kamailio server sends 404 not found error. I really have no idea how to set the configuration when using DNS loadbalance to return two NAT IP. Thank you , I'm looking forward from you! Sincerely yours Ada WU mlwu(a)south-star.com.cn

INFO: qq.com domain was blocked due to very high volume of spam

by Daniel-Constantin Mierla

Hello, writing to inform everyone that currently the qq.com domain is blacklisted by the kamailio.org email server due to high volume of spam sent to many admin addresses and mailing lists. Spamassassin had very hard time digesting and filtering, as content kept changing and addresses were random. I didn't get the chance yet to check if we have subscribers with this domain, so, as a fast lane, if you use it and don't have the possibility to quickly switch to another email server domain, write me to try to whitelist the address. Hopefully, if anyone is affected, there is not much inconvenience, but it was the only quick solution that could be applied for the moment.
