Dear Sirs,
being new to SIP and OpenSer, I have read the SIP introduction and
Admin's Guide, but there still is an issue that I could not find
information about.
I would like to set up a SIP infrastructure made of many UAs and one SIP
proxy (OpenSer). I want to bypass any NAT configuration so that I will
use UAs with STUN support and mediaproxy module on OpenSer; I will
perform billing (accounting) on the SIP proxy, so I will use record
route on OpenSer.
I want to make sure that my accounting will *never* be bypassed. This
seems quite difficult because the fields 'Contact' and 'Via' contain the
real address of the UA (or the translated one in case of NAT
configuration) and the SIP header will be fowarded to the other UA.
Sniffing the network for SIP packets, any user will be able to know the
real address of the UA and make direct call bypassing the SIP proxy.
How could I secure this situation, avoiding to forward Contact and Via
fields containing the real UA address? I was thinking if it is possible
to replace UA address with SIP proxy address, or would I break any
protocol rule?
Thank you in advance!!
Best regards,

Hi!
I've tried to compile the docs on ubuntu. It compiles without problems,
but the result is only garbage (tags mixed with text).
I never had issues on debian stable. Do I need a certain package? Has
anyone else seen such problems?
regards
klaus
I suggest you try to get it from onsip.org website
They have them.

Hi fellows
Our proxy is receiving some REGISTERs with wrong URI. The SOURCE PORT is inserted in it (the same number or incremented by 1). Our customers use Grandstream HT 486, 487. This problems is happening with 10 of them. This error happens just in REGISTER messages. If these customers make a call, they will talk without any problems. I can say this error isnt belong to a firmware version: some customers use the most new version and others of them use another. Did anybody already see this behavior?

Hi,
how can the dialog module help prevent the issue of missing BYEs?? Is dialog module capable of monitoring the sessions going on in openser.
I also wanted to ask that if i try limiting the no. of calls that per user can receicve how do i match the invite with the byes.
for eg: I may allow some users to have 5 incoming calls and other 2 and so on. So, I'll have to store that value in the DB table somewhere, and when a user receives a call, this column will be checked and the value should be decremented when he receives the invite message.
But how do i again increment the value, when the user receives bye. I mean how do i write the logic to match the invite and byes so as to increment and decrement the simultaneous calls value.
please help me regarding this....
thanks in advance.
jayesh.

Dear openser team:
Our company want to use openser develop our system.
Do you have any Developer's Guide about openser? we need some documents to help us
understand the openser's code.
The main difficulty is:
1. How to the openser init? where is the init code for rout list?
2. where is the code for receive sip message and send sip message?
We want to know the whole system's work logic and the program run flow.
Thank you for your help!

Hi All,
I need your help in installing and running OpenSER (www.openser.org
<http://www.openser.org/> ) on RedHat Linux 9.0.
I downloaded the latest tarball (openser_1.0.1-tls_linux_i386_tar.gz)
and installed it in /usr/local/sbin. But when I try to run by typing
"openser" at the prompt, I see the following error message:
"error while loading shared libraries:libssl.so.0.9.8: cannot open
shared object file : No such file or directory"
Basically I could not locate this library in the entire system. I even
tried installing the latest openssl library from www.openssl.org
<http://www.openssl.org/> ., but in vain.
Your help in this regard is highly appreciated.
Thanks & regards
Srinath
