Hi, we use pretty recent kamailio: ``` version: kamailio 4.4.0-dev2 (x86_64/linux) 1a758d flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, DBG_F_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 1a758d compiled on 14:49:47 Jul 20 2015 with gcc 4.8.2 ``` The case: consider the mobile SIP agent which switches between networks (e.g. wifi -> mobile) during the call. It sends re-INVITE with its new location. We use keep-alives provided by dialog module. And it seems that keep-alives don't use new address and are always sent to initial address. Any thoughts? Thanks. --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/273
