Consequently, next_gw fails. ### Troubleshooting #### Reproduction <!-- If the issue can be reproduced, describe how it can be done. --> kamailio.cfg: ``` loadmodule "lcr.so" ... modparam("lcr", "db_url", "cluster://cls1") modparam("lcr", "gw_uri_avp", "$avp(i:709)") modparam("lcr", "ruri_user_avp", "$avp(i:500)") modparam("lcr", "tag_avp", "$avp(lcr_tag)") modparam("lcr", "flags_avp", "$avp(i:712)") modparam("lcr", "defunct_capability", 1) modparam("lcr", "lcr_id_avp", "$avp(s:lcr_id_avp)") modparam("lcr", "defunct_gw_avp", "$avp(s:defunct_gw_avp)") modparam("lcr", "ping_interval", 60) ... route[LCR] { if(!($rU=~"^[+0-9]")) return; if(is_method("INVITE")) { if (!($fU=~"^[+0-9]+$")) { append_hf("P-Asserted-Identity: <sip:+49xxxxxxxxxxx@xxxxx.de>\n"); append_hf("Privacy: id\n"); $fn = "Anonymous"; $fu = "sip:+49xxxxxxxxxxx@xxxxx.de"; } if(load_gws(1, $rU, $var(caller_uri)) != 1) { xlog("L_ERROR", "Couldn't load gateways\n"); sl_send_reply("500", "Server Internal Error - Cannot load gateways"); exit; } else { xlog("L_INFO", "GW Selected '$avp(i:709)'\n"); xlog("L_INFO", "Domain of destination: $dd\n"); xlog("L_INFO", "To URI: $tu\n"); } if(!next_gw()) { xlog("L_WARN", "No gateway configured for $rU\n"); sl_send_reply("503", "Service not available, no gateways found"); exit; } else { xlog("L_INFO", "Calling the first matched gateway\n"); xlog("L_INFO", "ruri_user_avp: '$avp(i:500)'\n"); xlog("L_INFO", "To URI after next_gw: $tu\n"); xlog("L_INFO", "Request URI: $ru\n"); } t_on_failure("MANAGE_FAILURE_LCR"); route(RELAY); exit; } } ``` #### Debugging Data <!-- If you got a core dump, use gdb to extract troubleshooting data - full backtrace, local variables and the list of the code at the issue location. gdb /path/to/kamailio /path/to/corefile bt full info locals list If you are familiar with gdb, feel free to attach more of what you consider to be relevant. --> #### Log Messages <!-- Check the syslog file and if there are relevant log messages printed by Kamailio, add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). --> ``` Apr 15 20:59:27 x /usr/sbin/kamailio[879]: ERROR: <core> [core/usr_avp.c:152]: create_avp(): 0 ID or NULL NAME AVP!

Ideally, provide a pull request with a fix. --> As a workaround, I downgraded to kamailio 5.3.8 because the previous Ubuntu release 5.4.4 is not available anymore at http://deb.kamailio.org/kamailio54/pool/main/k/kamailio/ (why actually?) ### Additional Information * **Kamailio Version** 5.4.5 * **Operating System**: Ubuntu 18.04 <!-- Details about the operating system, the type: Linux (e.g.,: Debian 8.4, Ubuntu 16.04, CentOS 7.1, ...), MacOS, xBSD, Solaris, ...; Kernel details (output of `uname -a`) --> ### Root Cause Assumption https://github.com/kamailio/kamailio/commit/ca1821837dfe7dd6630f628d968ed4d… might be involved in the issue. -- You are receiving this because you are subscribed to this thread.
