### Description We have faced an issue which appears when TOPOH module is enabled, call is made from WebRTC client, then transferred by callee. #### Scenario WebRTC client behind load balancer makes call to softphone, call from softphone is transferred to external number using Asterisk. #### Expected result When call is hanged up on external number side, call should be hanged up on WebRTC client side. #### Actual result When call is hanged up on external number side, call is not hanged up on WebRTC client side. ### Troubleshooting #### Legend 10.5.0.145 - load balancer 10.128.150.67 - WebRTC client 10.181.0.1 - kamailio 10.5.2.192 - asterisk #### Log Messages On transfer: https://pastebin.com/H3FQ4Kpj On hangup from external number side: https://pastebin.com/wgfRzGbd On hangup from WebRTC client side: https://pastebin.com/sE0yhBae #### SIP Traffic Faulty case with TOPOH module enabled: [topoh_on.csv](https://github.com/kamailio/kamailio/files/11028205/topoh_on.… Normal behavior with TOPOH module disabled: [topoh_off.csv](https://github.com/kamailio/kamailio/files/11028206/topoh_of… #### Config files kamailio.cfg: [kamailio.txt](https://github.com/kamailio/kamailio/files/11028283/kamailio.… kamailio-local.cfg enabled toggles: #!define WITH_MYSQL #!define WITH_AUTH #!define WITH_USRLOCDB #!define WITH_DISPATCHER #!define WITH_HOMER #!define WITH_PSTN #!define WITH_TOPOH #!define WITH_CUSTOM_HEADERS #!define WITH_PROM #!define WITH_DMQ #!define WITH_NAT #!define WITH_XXXX_HEADERS #!define WITH_TLS #!define WITH_WEBSOCKET #!define WITH_VOIP_AUTH #!define WITH_ADVERTISE #!define WITH_JSONRPC #!define WITH_TCP #!define WITH_DIALOG #!define WITH_DIFF_PROVIDER_SRC_IP #!define WITH_UAC #!define WITH_DEV ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.6.1 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled on 09:11:15 Nov 15 2022 with gcc 9.3.0 ``` * **Operating System**: ``` dockerized kamailio running on Ubuntu 16.04.3 LTS Docker version 18.03.1-ce, build 9ee9f40 ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3398 You are receiving this because you are subscribed to this thread.
