Hi,

I have come accross an issue whereby when I replicate registration information to client nodes on the dmq bus, the AOR's of the client nodes for that replication event are garbled.

I am running the release version of kamailio v4.3.0 with the following 3 patches applied:

https://github.com/kamailio/kamailio/commit/894796f6f1fa2d2778ace5c56f58d204... https://github.com/kamailio/kamailio/commit/039231a3b61c00fe36e868417144daa9... https://github.com/kamailio/kamailio/commit/733fd5daf74963b152a2964f9eea1a6f...

``` # kamailio -V version: kamailio 4.3.0 (x86_64/linux) c6aa95 flags: STATS: Off, USE_TCP, USE_TLS, 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: c6aa95 compiled on 15:27:56 Jul 7 2015 with gcc 4.4.7 ```

Here is a sipgrep trace of the messaging of the UAC registering and the corresponding KDMQ messages sent to the 2 client nodes on the DMQ bus:

Here is the output of "kamctl ul show" on the node that the UAC registered on:

``` [reg01]# kamctl ul show Domain:: location table=1024 records=1 max_slot=1 AOR:: subscriber_name@subscriber_domain Contact:: sip:subscriber_name@192.168.1.238:54270;alias=212.2.160.202~57937~1;rinstance=f07ae8c64e7a1962;transport=UDP Q= Expires:: 22 Callid:: iwGubUeCiNBMYcFqL4Kf4g..

And here is the output of "kamctl ul show" on the two client nodes on the bus:

``` [reg02]# kamctl ul show Domain:: location table=1024 records=1 max_slot=1 AOR:: À.e

[reg03]# kamctl ul show Domain:: location table=1024 records=1 max_slot=1 AOR:: Àn" ```

My dmq related parameter settings are as follows:

``` # grep -i dmq module_definitions.cfg loadmodule "dmq.so" loadmodule "dmq_usrloc.so" # ----- dmq params ----- modparam("dmq", "server_address", DMQ_ADDRESS) modparam("dmq", "notification_address", "sip:sip-registrars:5060") modparam("dmq", "multi_notify", 1) modparam("dmq", "num_workers", 4) # ----- dmq_usrloc params ----- modparam("dmq_usrloc", "enable", 1) ```

The "sip-registrars" host/domain name resolves to the following 3 addresses (via DNS):

``` 10.6.0.173 10.6.0.174 10.6.0.175 ```

I am getting the following nathelper errors in the logs of the client nodes too, I presume, because of the garbeld AOR:
