Hello,<br>
<br>
first some clarifications about the subject:<br>
<br>
- append_branch() adds a new destination for normal
forwarding/relaying -- replies from these destinations are forwarded
back to the initial sender<br>
- t_replicate() creates a special branch -- replies from these
destinations are absorbed locally by the proxy<br>
<br>
Can you try using t_replicate() several times?<br>
<br>
Cheers,<br>
Daniel<br>

statements in stead of t_replicate as it does not appear to work
with 2+ servers to replicate to.<br>

<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) <br>

<br>
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. <br>

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 <br>
