<div class="moz-cite-prefix">Further update, it looks like
append_branch is over-writing the original request-uri, an ngrep
shows the following for the 2 messages sent:<br>
<br>
This one looks like the proper replicate for the original request<br>
<br>
U 2014/07/21 14:56:29.781372 BACKUP_REGISTRAR_1:5060 ->
BACKUP_REGISTRAR_3:5060<br>
REGISTER sip:<font color="#3333ff"><b>domain.com</b></font>;transport=UDP
SIP/2.0<br>
<br>
This one looks like the r-uri is re-written to that of the
BACKUP_REGISTRAR_2 address, but destination is still
BACKUP_REGISTRAR_3<br>
<br>
U 2014/07/21 14:56:33.781441 BACKUP_REGISTRAR_1:5060 ->
BACKUP_REGISTRAR_3:5060<br>
REGISTER sip:<font color="#3333ff"><b>BACKUP_REGISTRAR_2</b></font>:5060
SIP/2.0<br>
<br>
Is this normal operation or am I missing something fundamental
here with t_replicate/append_branch?<br>
<br>
Thanks<br>

an update on this, it appears to send 2 REGISTER requests in
parellel to BACKUP_REGISTRAR_3, so it looks like the append_branch
is being added but its uri is set to BACKUP_REGISTRAR_3 (and not
BACKUP_REGISTRAR_2 as requested int the append_branch section)

I have an issue that I cant seem to get to the bottom of, I
would appreciate if someone could point me in the right
direction.
<br>
<br>
I have 3 registrar's and would like to replicate the
registration regest from 1 to the other 2, I am trying this with
t_replicate, the docs say that to send to multiple destinations
an append_branch should be performed prior to the t_replicate,
which is what I am trying to do.
<br>
<br>
What appears to happen is that the replication only sends the
REGISTER to the server defined in the t_replicate command, it
doesnt appear to be sending it to the destination defined in
append_branch.

Here is what I have tried so far (on registrar 1):
<br>
<br>
#!define BACKUP_REGISTRAR_1 '1.1.1.1'
<br>
#!define BACKUP_REGISTRAR_2 '1.1.1.2'
<br>
#!define BACKUP_REGISTRAR_3 '1.1.1.3'
<br>
<br>
save("location");
<br>
if ( src_ip != BACKUP_REGISTRAR_2 && src_ip !=
BACKUP_REGISTRAR_3 ) {
<br>
append_branch("sip:" + BACKUP_REGISTRAR_2 + ":5060");
<br>
t_replicate("sip:" + BACKUP_REGISTRAR_3 + ":5060");
<br>
};
<br>
<br>
With the above in place, I only see the system attempting to
replicate to BACKUP_REGISTRAR_3, I dont see any request to
BACKUP_REGISTRAR_2.
<br>
<br>
Am I doing something wrong here?
<br>
<br>
Thanks
