Re: [OpenSIPS-Users] Best way to load data into local cache

[Schneur Rosenberg]

Why don't u use avp_db_query on demand and cache the info so u don't need
to run this particular query again?

[OpenSIPS-Users] Relay SCTP instead of UDP

[Moreira Yokoyama, Daniel]

Hi.

I'm trying to relay a message using SCTP instead of UDP.

I found some examples from people trying to relay using TCP and tried using the 
same approach, but using SCTP instead.

So, in my route script I did:

t_relay("sctp:10.0.8.108:5060");

I logged the state of my $du to make sure it was null at the time of the 
t_relay, but although I get SCTP init in the dump, the sip message is never 
sent and I have no error information.

After that I found other information about setting the forced socket ($fs) but 
still having no success.

Is it possible that opensips simply doesn't relay the message using the SCTP 
protocol? Or am I missing something?


Best regards.

[OpenSIPS-Users] [RTPENGINE] : OpenSIPS 1.11 : SRTP to RTP

[Dave Lechasseur]

Hi,

I have RTPEngine running on a Ubuntu Server with OpenSIPS 1.11.
Thought RTPProxy module I’m able to sends the RTP streams to RTPEngine.
Now I want RTPEngine to convert it to SRTP,  it seem that I need 
rtpengine_manage to do that but it’s not available in OpenSIPS 1.11 and I want 
to stay LTS.

Is there any other option to convert SRTP to RTP ?

Thank you,

[OpenSIPS-Users] Best way to load data into local cache

[John Quick]

Using version 2.1.1 of OpenSIPS
I want to load several hundred records into local cache memory on startup.
I've tried avp_db_query to read all data into an avp, then a loop to write
it from the avp into cache memory, but it can only do 100 records at a time.
Is this simply a limitation of all avp's?

Is there another way, a better way?

Why do I want to do this? Because I want to check each INVITE ruri
destination username against a list of known "suspicious" destination
prefixes (perhaps 1000 records). Each call may require several checks
because the list contains prefixes of varying lengths. I am concerned that
queries made directly to the MySQL table as each INVITE request is received
could impair performance and would put constant unwanted load on the MySQL
server.

Re: [OpenSIPS-Users] Permanent registration replication

[Bogdan-Andrei Iancu]

Hi Flavio,

By different IPs, you mean in the socket the contact record, right ? If 
you want to have different sockets on each server, maybe it is not a 
"replication" anymore - the basic concept of replication is to "copy" 
something on different servers. But you want different records, not the 
same record.


A really crazy idea is to use the AOR_INSERT event in usrloc (see 
http://www.opensips.org/html/docs/modules/1.11.x/usrloc.html#id295241) 
to trigger a script route when the permanent registration is added (of 
course you have to check the AOR to see if is a permanent or not, based 
on username, if possible). And from event route, use t_new_request (see 
http://www.opensips.org/html/docs/modules/1.11.x/tm.html#id295310) to 
build a REGISTER to go to the other servers, as a replicated register.

As said, this ^^^ is a bit SiFi :(

IMHO, you should stick to the idea of inserting the record on each 
machine, via MI . You mentioned some index issue - could you detail on 
this ?

Hi Bogdan ,

The binary replication does not support different IP addresses. There 
is no NAT in the implementation, so the idea is to replicate and set 
the local addres on each site.

Hi Flavio,

I haven;t tried, but MI registration may get replicated via BIN -
have you tried to set the BIN replication for usrloc (instead of
t_replicate) ?

Hi,

Does anyone has tried to replicate permanent registrations? For
normal registrations is possible to use t_replicate, but for
permanent inserted over MI, I don't know.

Inserting in two proxies at the same time using MI sometimes
generate duplicate index and abort the process and in some cases
remove all permanent records (using the same DB), I have tried.

Any clue helps,

Re: [OpenSIPS-Users] What cause TCP connection reset ?

[Hamid Hashmi]

Hi Răzvan
Thank you, I have already set the TCP chunk size to 8 but it was still showing 
"4 read attempts".
 Protocol TCPloadmodule "proto_tcp.so"modparam("proto_tcp", 
"tcp_send_timeout", 200)modparam("proto_tcp", "tcp_max_msg_chunks", 8)
but from your reply I thought that may there be an potion for TLS too :-p by 
increasing chunk size for TLS. 
 Protocol TLSloadmodule "proto_tls.so"
modparam("proto_tls","verify_cert", "1")modparam("proto_tls","require_cert", 
"1")modparam("proto_tls","tls_method", 
"TLSv1")modparam("proto_tls","certificate", 
"/path/to/certificate.pem")modparam("proto_tls","private_key", 
"/path/to/private_key.key")modparam("proto_tls","ca_list", 
"/path/to/ca_list.pem")modparam("proto_tls", "tls_max_msg_chunks", 
8)modparam("proto_tls", "tls_handshake_timeout", 119)modparam("proto_tls", 
"tls_send_timeout", 121)
It worked. :-) Cheers

This situation appears when a SIP message is sent in more than 4
"chunks" (this is tuneable). If the SIP message is too fragmented,
OpenSIPS closes the connection to prevent packets fragmentation
attacks.
