<tt>Hi Arsen,<br>
<br>
Yes, you can try setting the AVP in branch route - it will have
local (per branch only) effect, so you can do different values for
each destination.<br>
<br>
Best regards,<br>

<div>Hi guys,</div>
<div><br>
</div>
<div>I am trying to implement scenario when REGISTER
requests are replicated to more than one server.
Documentation says that each new server have to be added
using append_branch function.</div>
<div><br>
</div>
<div>So it will look like this:</div>
<div><br>
</div>
<div>append_branch("sip:<a href="http://reg1.domain.com"
moz-do-not-send="true">reg1.domain.com</a>")</div>
<div>append_branch("sip:<a href="http://reg2.domain.com"
moz-do-not-send="true">reg2.domain.com</a>") </div>
<div>t_replicate("sip:<a href="http://reg3.domain.com"
moz-do-not-send="true">reg3.domain.com</a>")</div>
<div><br>
</div>
<div>The servers must communicate via TLS. All servers
form a cluster and share one main domain (tls default
domain) for end users. For intra-servers communication I
use self-signed certificates and mod tls_mgm. </div>
<div><br>
</div>
<div>Replication only to one server works fine, I select
client_domain by setting $avp(tls_cli_dom) avp right
before t_replicate("<a href="http://reg2.domain.com"
moz-do-not-send="true">reg2.domain.com</a>");</div>
<div><br>
</div>
<div>Now the issue: what is the best way to set
client_domain avp for each particular domain in the
cluster so, for example, to replicate to <a
href="http://reg1.domain.com" moz-do-not-send="true">reg1.domain.com</a>
opensips will use client crt for reg1, for <a
href="http://reg2.domain.com" moz-do-not-send="true">reg2.domain.com</a>
cert for reg2 and so on.</div>
<div><br>
</div>
<div>can I set client_domain_avp in the branch route? </div>
<div><br>
</div>
<div>branch_route[1] {</div>
<div><br>
</div>
<div>if ($rd == "<a href="http://reg1.domain.com"
moz-do-not-send="true">reg1.domain.com</a>")</div>
<div> $avp(tls_cli_dom) = "reg1";</div>
<div> else if ($rd == "<a href="http://reg2.domain.com"
moz-do-not-send="true">reg2.domain.com</a>")</div>
<div> $avp(tls_cli_dom) = "reg2";</div>
<div>...</div>
<div>}</div>
