Hi Daniel,
``` version: kamailio 4.4.0-pre1 (i386/linux) c5289e-dirty flags: STATS: Off, EXTRA_DEBUG, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, 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_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: c5289e -dirty compiled on 16:23:17 Mar 3 2016 with gcc 4.9.3 ```
I don't see negative values anymore, so this is better.
But if I use Expires: 4294967295 in my subscribe (and presence max_expires fixed to 4294967295) here is what I get:

Looks like the Expires value is divided by 2 or one bit is disappearing.
