[OpenSIPS-Users] Are alias_db_.. blocking functions?

2020-05-18 Thread John Quick
Please can someone confirm if alias_db_lookup() and alias_db_find() are
blocking functions.
If they are, can they be used in the async function?
I'm using v2.4.6 and 2.4.7 of OpenSIPS.
Thanks.

Re: [OpenSIPS-Users] rtpengine documentation

2020-05-18 Thread Callum Guy
Hi Rob,

I'm interested to follow your thread to hear more about this, I have
found that some flags are valid yet undocumented during initial setup
of some RTC compatable proxies.

Two in particular: DTLS-passive and SDES-disable both of which appear
to influence behaviour of RTPEngine in accordance with the RTPEngine
documentation.

YMMV however it might help you to try this format as you proceed with testing.

Good luck!

Callum

Re: [OpenSIPS-Users] UDP fragmentation in reply routes

2020-05-18 Thread Maxim Sobolev
Smells like a OS/kernel bug to me. There is little application can do in
that regard, UDP fragmentation/reassembly happens at much lower layers of
the OSI stack.

However, as a workaround as long as SIP goes you can try to reduce your SIP
signalling packet size by using compact version of SIP headers, as well as
dropping headers that are not used. That would save you 100-150 bytes per
SIP message perhaps. I don't know if OpenSIP can do that in the proxy mode
out of the box though, so you might want to add b2b into the flow.

[OpenSIPS-Users] UDP fragmentation in reply routes

2020-05-18 Thread Olle Frimanson
Hi,

 

We have an issue on our home proxy (opensips 2.4.6), when it receives  200
OK (over UDP)  from our Freeswitch and the package size is higher than the
MTU size , we sometimes get fragmentation  of the UDP packets, but only the
first part of the fragmented package is sent to our edge proxy. Is this a
known issue or is it a OS bug?

 

We have not yet spotted any pattern on this and in most cases bigger packets
with MTU around 1600 bytes gets through without an issue.

 

I can add that in the other direction in the normal request routes we don't
have any issue at all can have packets > 2000 bytes without any issues.

Does Opensips use IP_MTU_DISCOVER or how is fragmentation controlled and is
it expected to have different behavior in reply routes vs other routes?

We use Centos 7 in a virtual server environment.

 

I was hoping someone can share some light on this strange issue.

[OpenSIPS-Users] Running OpenSIPS on same box as Asterisk/FreeSwitch

2020-05-18 Thread John Quick
Whenever I have tried to run OpenSIPS on the same host server as either
Asterisk or FreeSwitch (using different ports), I have always hit a snag
with routing of sequential loose-routed requests. Possibly this only happens
when using double Record-Route headers which I need for protocol conversion
(TLS to UDP or TLS to TCP).

Where the address in the topmost Route header is the same as it's local
address, OpenSIPS copies the URI (and parameters) from a Route header to the
R-URI which, in this use-case, causes the request to loop back to itself. It
should instead delete the two Route headers and copy the URI value from the
Contact header, picking up the correct port for the Asterisk/FreeSwitch app.

I've tried Googling to see if others have experienced this, but didn't find
any nice solution other than using two IP's on the same box.
A post from Flavio mentions this problem in June 2013. Is there a simple
solution?

Re: [OpenSIPS-Users] Running OpenSIPS on same box as Asterisk/FreeSwitch

2020-05-18 Thread James Hogbin
I thought I had just done some bad config.  I have almost exactly the same 
thing.

I have Freeswitch And Opensips on Azure VM’s

Freeswitch = 10.0.0.4 + External IP
Opensips = 10.0.0.5 + External IP

Both are configured to use the external addresses

Freeswitch will start the conversation on its external Gateway IP address with 
the Opensips external IP address

However the moment I put the Record_Route in the message to Teams Freeswitch 
starts using the local 10.x.x.x. address on opensips rather than the external 
address for ACK and BYE which rogers the whole thing up.

I’m sure there is probably some way to fix it in the opensips plan as the 
dialog/transaction ID’s are still there but it’s beyond me.

[OpenSIPS-Users] [Blog] Cross dialog data accessing

2020-05-18 Thread Bogdan-Andrei Iancu


There are several calling scenarios – typical Class V – where multiple 
SIP dialogs may be involved. And to make it work, you need, /from one 
dialog, to access the data that belongs to another dialog/.

Hi Mark,

First of all, all the upgrades are incremental, from one version to next

Secondly, we haven;t yet prepared the migration docs/scripts for 3.0 ->

Re: [OpenSIPS-Users] OpenSIPS cdr variables

2020-05-18 Thread Bogdan-Andrei Iancu

Hi Asteriskman,

As per doc [1], the module will provide the timestamp of the 200 OK 
(call answering) . If doing "cdrs", you will also get the call duration, 
already computed.


For anything extra, you should use extra accounting data [2].

The accounting engine does not natively support noSQL backends, but you 
can use the accounting CDR event [3] in script [4] in order to perform a 
raw mongo query [5].



[1] https://opensips.org/html/docs/modules/3.0.x/acc.html#overview

[2] https://opensips.org/html/docs/modules/3.0.x/acc.html#ACC-extra-id

connect timestamp(200 OK) and end timestamp(BYE) in MongoDB.

Now my questions are
(1) What is the best way to get those values in opensips script? Use 
$Ts at different stages and store the values in dialogue?
(2)What is the best way to perform insert into MongoDB? I see there is 
a cachedb_mongodb module and you can use cache_raw_query.

(3)Will my above approaches work when I do parallel forking too?

Re: [OpenSIPS-Users] Are alias_db_.. blocking functions?

2020-05-18 Thread Bogdan-Andrei Iancu

Hi John,

Yes, these functions are performing DB queries in runtime and these 
queries are potentially blocking.


The db_aliases module does not offer async support, but the queries it 
is doing are trivial and you can do them via avp_db_query() + async() 
support.

Hi Bogdan-Andrei,

Yes, I know, but I meant similar to $T_fr_timeout and
$T_fr_inv_timeout, which can be set in the script during message
processing.
Sorry if my questions wasn't clear enough.

Regards,

Grant

Hi Grant,

There are the 'T1_timer' and 'T2_timer' module parameters for that.

Hello,

I couldn’t find anything related to adjusting the T1 and T2 timers on a per 
transaction basis, similar to the fr and fr_inv timeouts.

Is there a way in OpenSips to adjust these values at runtime?

Regards,

Grant

Re: [OpenSIPS-Users] OpenSips Configuration with RTP Proxy

2020-05-18 Thread SamyGo
Hi,

Could you share further details as whats not working?
check the following:
1 - OpenSIPS is able to connect tot he rtpproxy socket
2 - OpenSIPS is calling the right rtpproxy function from the script
3 - the RTPproxy function have correct parameters
4 - Check the SDP for incoming leg and the outgoing leg and check if
rtpproxy is modifying it or not at all.

Regards,
Sammy
