Maybe you should look into GRUU stuff ;).<br>
<br>
On the TCP error - even if you set the TCP persistence flag, the
UAC may close the TCP conn -> you end up in the same
situation. What you can do is to prevent OpenSIPS to open TCP
conns when routing to end-users - the idea is to have end-users
connecting to OpenSIPS and not the other way around. See
"tcp_no_new_conn_bflag" :<br>

<div>Hi Bogdan,<br>
</div>
So I thought of doing this and I have another problem. Say
if a device registered from IP 1.2.3.4, and then moved out
to different network and re-registered from IP 4.3.2.1,
there is a stale registration lying in opensips for the same
device from 1.2.3.4.<br>
</div>
Now when I use TCP as transport, opensips waits till connect
timed out on unreachable IPs before sending the call to
registered contact and the following messages are logged in
syslog:<br>
ERROR:core:tcp_blocking_connect: timeout 10 s elapsed from 10
s<br>
ERROR:core:tcpconn_connect: tcp_blocking_connect failed<br>
ERROR:core:tcp_send: connect failed<br>
ERROR:tm:msg_send: tcp_send failed<br>
<br>
</div>
<div>Looks like opensips tries to do a TCP connect first with
all registered contacts before actually routing the call.<br>
</div>
<div>I do,<br>
modparam("registrar", "tcp_persistent_flag", "TCP_PERSISTENT")<br>
<br>
if(is_method("REGISTER")) {<br>
setflag(TCP_PERSISTENT);<br>
setbflag(30);<br>
if(!save("location", "fc1")) {<br>
t_reply("500", "Error while saving AOR");<br>
}<br>
}<br>
<br>

Basically you do not what to have more registrations
from the same IP, right ?<br>
<br>
Exactly the opposit of the is_other_contact() function

<div>Hi,<br>
</div>
I am trying to solve a problem of having
one registration per AOR per device. So
user 1234 can register from device A,
device B and device C. But the user 1234
should not have multiple contacts from
device A alone. <br>
</div>
At times when the device loses network,
proxy doesn't receive de-register and the
contact stays in opensips till its expiry
time. So the same device is thus capable of
creating multiple contacts. I could solve
this by using "fc1" flag while doing a
save("location") but I need multiple
registrations to be allowed from different
devices !!<br>
</div>
So is there a way where while doing a
save("location"), I set some sort of device id
along with it such that I identify and
overwrite the existing contact only if the
registration comes from same device-id or else
add it up for parallel forking.<br>
</div>
Do let me know if I make sense here and there's
a solution to this. Thanks for any suggestions
and directions.<br>
<br>
Thanks,<br>
<br>
