Hello guys,

My kamailio version is:

version: kamailio 5.1.1 (x86_64/linux) 
flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, 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.

I am facing a strange bug with TM in case of negative replies.

A party sends the invite 
B party connects the call
B party after a few time sends in dialog invite with t38 media.
A party rejects the in-dialog invite with 488
Kamailio send ACK to A party(since it is an ACK for negative replies it is build in each hop)
The problem in this case is that the ACK sent by kamailio to A party has the callid of kamailio - B party.
Since it has a different callid the A party does not recognize the ACK.

How can I resolve this issue?

Thanks and regards,
Rafael
