<font face="monospace">Hi Denis,<br>
<br>
Could post the actual Contact hdr as received (network level like
pcap or trace) by OpenSIPS from both caller and callee parties ?<br>
<br>
Regards<br>

<div>Hi all,<br>
<br>
My network scheme is <br>
softphone <-nat-external network-nat-> opensips
<-local network-> sip servers <-local network->
softphone<br>
No b2b or topology_hiding modules are used.<br>
</div>
<div>Opensips versions I tried: 3.4.4-1 and 3.4.3-1.</div>
<div><br>
I make a call from a phone behind nat to sip server via
opensips, so I use the fix_contact function from
nat_traversal/fix_nated_contact from nathelper for each
request.<br>
On the first invite I get "caller_contact":
<a class="moz-txt-link-rfc2396E" href="sip:1002@3.3.3.1:49682;transport=TCP;ob">"sip:1002@3.3.3.1:49682;transport=TCP;ob"</a> in "opensips-cli -x
mi dlg_list".<br>
If caller side makes re-invite, then i see this
"caller_contact": "\u0001" for nat_traversal, <br>
and this "caller_contact": "<a
href="mailto:sip%3A1002@3.3.3.1" moz-do-not-send="true">sip:1002@3.3.3.1</a>\ufffd"
with nathelper in dlg_list.<br>
In that case dlg_send_sequential mi dialog function cannot be
used cause caller contact cannot be read.<br>
<br>
Also if i make a re-invite from the caller side then the
caller_contact field in dlg_list starts looking normal.<br>
<br>
Am I doing something wrong with fixing the nated contact
field?<br>
