Re: [OpenSBC] openSBC upper registrar related problem

[deveshbissa <bis...@ya...>]

Hi Joegen,


Thank you for your reply.But i am encounter with loop in routes .


with my same configuration of opensbc and changed configuration of sjphone(as suggested by you before ,proxy domain---- ipofSBC:portofSBC and user domain--- registrardomain:registrarport) i have tried to  send register request to pcscf. But there(at pcscf ) it show message sent by--- ipofregistrar:portofregistrar  instead of sent by ---ipofSBC:portofSBC. It also showing error "message does not contain autharization header" at pcscf.Please help me.


Thank you,

[OpenSBC] OpenSBC with 3Com VCX

[Ole B. K. <ob...@te...>]

Hello,

I have installed osbc on a debian etch. With help from the documentation 
most of the time was spent waiting for compilation to finish. So with 
very little effort I now have osbc up and running. My intention is to 
put our 3Com VCX system behind the osbc so that all sip messages and rtp 
traffic is routed through osbc when communication with other sip 
servers/providers. The problem is that the dial domain in the 3Com VCX 
is an ip address (it cannot be a domain name) and the ip address is the 
same as the ip address of the primary server. I've tried different 
settings to get this to work - with no luck. My question is: is there 
any chance that this will work - or should I stop wasting any more time 
on this?

Hacks are welcome, I will happily recompile, produce logs, extensive 
testing and feedback to make this work.

Regards,

Ole Kaas

[OpenSBC] Log files management problem

[Jack D. <455...@gm...>]

Hello,

Looks like there is a problem in the log files management when we switch
to a new day.  A new logfile seems to be created for SIP Log, but the PTRACE
log keeps using the file the OSBC opened at startup.
Can anyone confirm that bug ?

Im running OSBC 1.1.5 on Solaris 10.


Also, is there a way to save the entries currently in the registrar memory
when operating in B2BUpperReg mode so that a server reboot or simply OSBC
restart keeps the user location states ?  SER does it that via a DB.

Thanks,

JD

Re: [OpenSBC] opensbc with FOKUS openims

[Joegen E. B. <joe...@gm...>]

Devesh,

Yes this is the right way.  You are also in the right track by using 
B2BUpperReg mode.  Juut make sure you configure SJPhone properly.

Set Outbound Proxy  = OpenSBC IP:port
Set Domain = pcscf domain:port

Re: [OpenSBC] openSBC upper registrar related problem

[Joegen E. B. <joe...@gm...>]

Davesh,

For Upper registration to work, make sure that mydomainname.org does not 
resolve back to OpenSBC or else it won't try to relay the 
Registration.   Try making mydomainname.org to resolve to  
sip:ipofregistrar:port instead.

Paul,

Did you set the "Static Media Address" in the general parameters to 
point to the public IP of your router?

[OpenSBC] iptables

Can anyone tell me what the good iptables settings are to make OpenSBC work behind NAT (iptables)


At the moment i have set it like this (see further).  


I can register .... but i don't hear a thing not from inside and not from outside the router.

Re: [OpenSBC] openser + opensbc as nat

[Eric H. <ope...@op...>]

On your question regarding NAT, OpenSBC is designed to have a public IP address on at least one network interface.  It is possible to use OpenSBC as a bridge between public and private networks, but it is not possible (at least not currently) for OpenSBC to communicate with UAs on the public Internet if it is behind NAT.

Re: [OpenSBC] openser + opensbc as nat

[Eric H. <ope...@op...>]

OpenSBC is being used in stable production environments by several service providers that we know of.  At Solegy alone, OpenSBC handles transactions for hundreds of thousands of end users and processes millions of call attempts daily.  The capacity of a single instance will vary depending on your usage scenario, however you can expect an instance running on an avaerage server (in B2BUA mode with media proxy enabled) to handle several hundred concurrent calls and many thousands of registered users.  Higher capacities may be achieved by using load-balancing techniques.


If you are interested in a commrcial support arrangement from the people that created OpenSBC, Solegy offers several options check here:

Re: [OpenSBC] openser + opensbc as nat

[vics <vic...@gm...>]

Hi, 


is opensbc stable enough to put it in a production environment? I mean to handle thousands of call streams, and do you know any how on how to get it done?


 


Thanks so much..  

Re: [OpenSBC] OpenSBC session supervising

[Eric H. <ope...@op...>]

The way to accomplish this is through the use of the SIP Session Timer, which must also be supported by any connecting endpoints.  More details can be found here:

http://www.jdrosen.net/papers/draft-ietf-sip-session-timer-14.txt

Re: [OpenSBC] openser + opensbc as nat

[Joegen E. B. <jb...@so...>]

OpenSBC default behavior is to only proxy NAT when the call comes from a private address or is terminating to one.   There is no need for a reINVITE to have media flow directly between UA for public-IP calls.  Your question is not obvious but I suppose you are asking if you could replace media proxy with OpenSBC?   Then the answer to that is yes.

[OpenSBC] openser + opensbc as nat

[vics <vic...@gm...>]

Hi,


 I have an openser + mediaproxy server, I want to use opensbc to be my Nat server that handles my RTP stream , because mediaproxy proxyes everything, it does not have P2P stream like in asterisk canreinvite, but may be any one have done it before, and if so please give a clue..


 


Thanks so much..

Re: [OpenSBC] Interim Code for CALEA support

[OpenSBC] Interim Code for CALEA support

[Joegen E. B. <joe...@gm...>]

Hi Everyone,

I have recently added a new trunk in OpenSBC called CALEA trunk (refer 
to SBCCALEATrunk.cxx).  What this is, is a separate trunk that handles 
processing of packets for lawful intercep as mandated in CALEA 
(Communications Assistance for Law Enforcement Act).  Take note that 
this code is in its infancy and is not complete yet.  As of the moment, 
only the capability to save sip packets to pcap format is in place (rtp 
packets to follow).   Slowly the CALEA trunk will evolve into a fully 
functional LEA collector.

To test, look for the new section in http admin name "CALEA Calls".  You 
will find a text box here name CALEA Filter.   This should contain a set 
of comma delimited SIP URIs that you want to intercept (wild cards 
accepted).  Example:  sip:1111*, sip:2222*

All calls beginning with 1111 and 2222 will be intercepted by the CALEA 
trunk.   The PCAP dump will be saved in $(OPENSBCDIR)/calea/pcap directory.

CAVEAT:  There is still a bug in PCAFile.cxx that wrongly computes the 
ip checksum of the packets.  This will show in ethereal.  This error is 
considered benign.

Dear Joegen,

Thank you for your help. The problem was what you suspected. The dns mapping was missing for scscf.mik.bme.hu (I added only mik.bme.hu).

Now opensbc works fine between our IMS and SIP systems!

Best regards,
 madar
