Hi Jimmy,<br>
<br>
Anthony M. wrote on a (quite old) mailing-list topic the following
information:<br>
<blockquote><i>also you can set
</i><i>sip_sticky_contact=true
</i><i>channel var which will make that session turn on nat lock
in the b leg </i><i>so they can't change the contact to a nat
addr
</i><i><br>

add it in {} to your dial string like
"</i><i>{<a class="moz-txt-link-abbreviated" href="mailto:sip_sticky_contact=true}sofia/internal/foo@bar.com">sip_sticky_contact=true}sofia/internal/foo@bar.com</a>

Could be great if someone with the rights could update <a

then :)<br>

<div class="moz-cite-prefix">Hi Florent,<br>
<br>
The parameter sip_sticky_contact solved my problem, too.<br>
Since there is no docuementation about this parameter, do you
know what does the parameter exactly do?<br>
Is there any side effect that I turn it on?<br>
<br>
Thanks,<br>

<br>
Have you tried "sip_sticky_contact=true"?<br>
(there's no documentation but here's the wiki page: <a

href="http://wiki.freeswitch.org/wiki/NAT_Traversal#sip_sticky_contact">http://wiki.freeswitch.org/wiki/NAT_Traversal#sip_sticky_contact</a>)<br>
I had kind of same issue as you and this solved my problem!<br>

<br>
I've tried NDLB-connectile-dysfunction, but to no avail.<br>
SIP_Client1 and SIP_Client2 are all in the same 3G network,
so I couldn't figure out why FS treated them in different
ways.<br>
<br>
Thanks.<br>

<div>When a client is behind NAT that can mean the client

We have two different SIP Clients and they all use 3G
to connect to FS.<br>
SIP_Client1 receives BYE without problem but
SIP_Client2 couldn't.<br>
In the SIP_Client2 case, I don't understand why FS
sended BYE to<br>
100.77.163.183 rather than 42.71.215.54.<br>
Here are the snippet of FS log.<br>
