This is when the sip message was sent from a.b.c.d and the Via header
has x.y.z.w. if you get a pcap with the request, we can check and see if
the test is true for it.

On the other hand, you should use
set_contact_alias()/handle_ruri_alias() instead of fix_nated_contact()
(see how default kamailio.cfg does it) -- it is safer for such cases and
avoids getting in troubles with devices that are strict in checking if
the r-uri is the contact they set previously.

Cheers,
Daniel

In Noah's case, this posed an issue because the request was being 
received from a proxy. The proxy strips off its Via, and the topmost 
exposed Via has the network & transport-layer reachability information 
of the UAS that received the reinvite (originated on Noah's end). Both 
proxy and UAS are public, but different entities.



On the other hand, you should use
set_contact_alias()/handle_ruri_alias() instead of fix_nated_contact()
(see how default kamailio.cfg does it) -- it is safer for such cases and

Agree. I have moved to this nowadays for all cases that were handled 
with fix_nated_contact() in the past for just this reason.

[SR-Users] To/From tags in uac_req()

2016-08-18 Thread Julia Boudniatsky

Hello,

Is it possible to set To/From tags in uac_req() ?
We want to implement service like "color ring back tone".

*Kamailio  uac* *Asterisk*

INVITE SDP -->
<-200 SDP--
-BYE  -->
<--- 200   ---

I need to send in BYE the same tags.
Kamailio 4.4.2.

Thanks,

Hi Julia,

The only attributes that can be set on a request formed with uac_req() 
are listed here:


http://www.kamailio.org/wiki/cookbooks/4.4.x/pseudovariables#uac_req_key

Tags are not among them.

However, it might be possible to generate a completely synthetic SIP 
message yourself using an alternate facility:

an alternative is to track the call with dialog module and then trigger
the end of the dialog via config or mi/rpc:

Hello Daniel,

How to track with dialog the call initiated by Kamailio ?
Simple dlg_manage(), after uac_req_send()?

Thank you,

[SR-Users] Howto timeout INVITEs over TCP to something < 30s?

2016-08-18 Thread Daniel Tryba

If an enduser INVITEted over TCP t_set_fr(t) with t < 30s have no
effect, the INVITE will always timeout after 30s. What is controlling
this 30s? The only default at 30s is the fr_timer, which should have no
part in the timeout between an 1xx and a final answer for an INVITE.

[SR-Users] Running both 4.3 and 4.4 with the same database with permission module

2016-08-18 Thread Daniel Tryba

I want to upgrade my cluster from 4.3 to 4.4, beginning with the spare
for live testing. But since there is a change to the trusted table
(which we don't use, only address) this isn't possible without some
tricks. There is no override for skipping the version check on any
permissions table.

I need to share the subscriber/location/address/usr_preferences and
db_aliases tables between the 4.3 and 4.4 machines. The only thing I can
think of is:
-patch the permissions module to accept the old version of trusted
-create a 4.4 database and use federated tables to access the 4.3 data

Not hard to implement any of these 2, but some other modules have the
option to skip these checks, eg: 
http://www.kamailio.org/docs/modules/4.4.x/modules/auth_db.html#auth_db.p.version_table

Is there a reason not all modules have this flag (which you could use at
your own risk)? Or am I missing something here?

The changes are backwards compatible with the old version. You can just use 
another "version" table on the new instance.

http://sip-router.org/wiki/cookbooks/core-cookbook/devel#version_table

Seems docs haven't made it to kamailio.org.

IMHO that option needs to be removed.

[SR-Users] detect failed socket

2016-08-18 Thread Péter Barabás

Hello,

I want to refine the instant message handling in our application. It works 
really fine in most cases. I use the msilo module to store offline messages if 
the user is not registered with sending PUSH notification.
But, there is a situation when I have problems:
When I send a message to a user whose phone is in airplane mode. In this case 
his location record exists but the communication on the socket is not possible 
and the client timed out the request.

Is it possible to check the socket towards the receiver user at the moment when 
the message arrives at Kamailio? I think if I would check that if the socket is 
not fine, I could send the message to the msilo directly and the client would 
not have wait for timeout to resend.

Thanks.

Peter

Perfect. Just what is needed in this kind of scenario. But before this
goes to kamailio.org:

This example isn't correct, it's version_table not table_version
according to 4.4.x cfg.lex

[SR-Users] Call forking with delay

2016-08-18 Thread Igor Potjevlesch

Hello list,

I have a proxy that manage fix calls and a proxy that manage mobile calls.
I want to implement call forking so when I call to a fix phone the call
goes to the fix proxy and it forks to the mobile proxy who manage the call
and viceversa. I want the fix to ring 2 or 3 times before the mobile.

In order to do so in my fix proxy I added a diversion field with the reason
"forking" and in my mobile proxy I check if the reason is "forking" to wait
with the fonction "async_route" from the ASYNC module. When I call the fix
I can fork to the mobile with delay without any problem because in that
case my fix proxy manage one call and my mobile proxy the other one.

But when I call the mobile the call doesn't even get to my fix proxy
because my mobile proxy has to make the original call to wait while he is
forking the fix call to my other proxy. And i think that calling the
async_route fonction makes both calls to wait.

My code is:

Fix proxy:

if($tU==123456789){
   add_diversion("forking");
   append_branch("sip:987654321@proxy_mobile");
}

Mobile proxy:

if($tU==987654321){
   $var(z) = "1";
   append_branch("sip:123456789@proxy_fix");
}


route[INVITE]{

if($dir == "forking"){
   async_route("RELAY", "7");
}else if($var(z) == "1"){
   async_route("RELAY", "7");
}else{
   route(RELAY);
   exit;
}

}


How can I differentiate in the second scenario when I call the mobile phone
to fork to the fix phone?

Thank you for your help.

Igor.
