hi
Thanks for the answer.
But again sorry ,i am geeting 408 request time out again.
I have changed the via-stack as was in the request

hi all,
We are getting 408 request timeout for our SUBSCRIBE method inspite of other Useragent sending
a 200OK response for the SUBSCRIBE method.
Both SUBSCRIBE and 200OK packets are getting proxied to respective user agents correctly.
But the client1 is receiving 408 request time out error and the client2 is receiving SUBSCRIBE methods often.
The SUBSCRIBE packet and the 200OK packet are as shown below.

Thanks

FYI
We found some SIP widely used implementations don't like loose-routing
parameter (";lr") without any value (which is the currently documented
use of loose-routing) and break. We will probably introduce a workaround
option which will allow to use lr with value (e.g., ";lr=true").
In particular, we learned that Windows Messenger, rejects loose-record-routed
requests and replies with "400 BAD Request" to INVITES with ";lr" in it.
Cisco IOS strips all RR parameters without value away, including ";lr" from
Route header fields in subsequent requests.

Hi all,
I downloaded the latest code from CVS and trying to
include Presence Agent(pa.so) in my ser.cfg file.
While trying to start the SER, i am geting
"Segmentation fault" error. I have included dependent
modules (tm,usrloc,jabber) before loading pa.so inside
ser.cfg. Is there any special parameters to be passed
for pa.so module through modparam ?
Also is there a client test program available to test
Presence module ?
Thanks,
Santosh

Hi,
I got Pingtel, SipTone hardphones and Windows Messenger softphone to
work just fine with the SER 0.8.9 server on the Internet via a Intertex
IX66 firewall.
I tweaked the SIP phone configurations to use the SER 0.8.10 I installed
at home, from the binary RPM obtained from
ftp://ftp.berlios.de/pub/ser/0.8.10/packages/redhat/7.x. I ran into
some very strange behaviors with SER and the firewall. I disconnected
the firewall connection to the Internet and the SIP INVITE transactions
stopped involving the firewall. This was evident from analyzing
Ethereal captures. (It was if the firewall was in a promiscuous mode of
operation an acted upon packets that did not apply to it.)
However, I still could not get INVITE transactions to generate 2xx
responses for two local phone and SER proxy configured without
authentication. So, I tried compiling the source code on my Redhat 7.3 box.
> gcc -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-110)
> make config <- for SER
.
.
.
Old gcc detected (2.9x), use gcc >= 3.1 for better results
make: *** No rule to make target `config'. Stop.
My question is should I compile SER with the GCC 2.96 compiler or pay
attention to the make config message and update GCC? (Some of the RPM
binaries differ from what I compiled with the default RH 7.3 GCC 2.96
compiler.)
Sincerely,
Scott Holben (skaht(a)iptel.org)
Hi all,
I just installed MySql server on my linux box and
trying to start SER. I am geting an error message
while staring SER:
"connect_db(): Cann't connect to local MySQL server
through socket '/var/lib/mysql/mysql.sock' (2)"
My MySql serevr is runing and I can connect to SER
database from my machine. However the socket is
created at /tmp/mysql.sock. Now my question is, from
where did SER pickup the socket path while starting ?
How can I change it to /tmp/mysql.sock ?
Any pointer is appreciated.
Thanks and Regards,
Santosh

I've discovered a bug in SER 0.8.10 which can segfault the server with a
dereference of NULL, one time in RAND_MAX.
In the function branch_builder() in msg_translator.c, if both the parameter
'label' and the parameter 'char_v' are 0, SER will crash. This is because
the code assumes that if label is 0, char_v is non-NULL, and so will attempt
to call memcpy() with char_v as the source.
When branch_builder is invoked by the tm module, however, the label
parameter comes from a random value assigned by h_table.c. This value is
generated by rand(). As such, its value can legitimately be 0, which will
happen, on average, one time in RAND_MAX.
On Linux, RAND_MAX is 2^31, so this crash is very unlikely. However, on
Solaris (where I'm doing some testing), RAND_MAX is 2^15, so this crash is
reasonably common for a server under heavy load. However, this is a "valid"
crash in either case; this isn't just a portability issue.
(Note that RAND_MAX == 2^15 being less than TABLE_ENTRIES == 2^16 can also
cause problems, according to a comment in h_table.c, though I believe only
ones of efficiency, not correctness.)
The patch below works around the problem in the simplest possible way,
though it isn't a correct fix. I suspect the proper solution would be a) to
reverse the logic of branch_builder() to test char_v for NULL, rather than
label for non-0; and b) to check with the preprocessor if RAND_MAX is less
than TABLE_ENTRIES, and if so, use random() rather than rand() in
modules/tm/h_table.c.

Hello!
I'm interested to implement the possibility of call between
two NATted ATAs using SER 0.8.10 and Maxim's nethelper module.
I'm using config described at
http://lists.iptel.org/pipermail/serusers/2003-January/000165.html
Signalling works just fine, but no media stream.
My test setup:
ATA1 --- NAT1 --- SER --- NAT2 --- ATA2
cut from tcpdump of call from ATA1 to ATA2 on private side of NAT1:
213.186.192.26 is NAT2
