Hi,
I am have managed to create the zone file, (sipserver.ipaxiom.com) and have
tried running the command
[root@sipserver saber]# dig -t SRV _sip._udp.sipserver.ipaxiom.com
; <<>> DiG 9.2.1 <<>> -t SRV _sip._udp.sipserver.ipaxiom.com

as you can see u I do not get the answer from the server. I am may have done
something wrong, I have included the sipserver.ipaxiom.com.zone file
You may be able to point me in the right direction.

Due to a known limitation in the Cisco IOS, it is not possible to restrict the duration of a call on a Cisco gateway. Since I have been hit by this a couple of times - one time having 6 timeslots on an E1 open for 3 days - I would like to hear any suggestions on how to remedy this utilizing the SER.
Feel free... :-)
Sincerely,
Peter
Hi :
I have download the latest ser and all modules with CVS (2004/04/21)
i still testing the same environment with nathelper , rtpproxy
UA 1(kphone 3.14) -> NAT -> Ser <- UA 2 (kphone
3.14)
UA1 can register to ser with public (after NAT ) correctly ,
but when UA 2 INVITE UA1
When UA1 reply 200 OK with SDP
Ser seems not modify the SDP to public ip and port
so when UA2 receive SDP , it still can't know or should say it can't send
rtp to correct IP:port
it seems my config has some bug , so sdp has not been modify ??
can any one give my any ideas?
and
in this scenario , is ser modify the sdp to force UA to send rtp to ser
then rtpproxy will handle the both UAs' rtp to transport to the both UAs?
these are my ser.cfg refered from
(http://www.informatik.uni-bremen.de/~prelle/terena/cookbook/main/ch04s07.ht
ml )

In the current CVS unstable version there seams to be a bug in the
ser_mysql.sh:
I have tried to upgrade from my stable 0.8.12 to the CVS unstable and
found the following issues:
bhoeneis@wil:~/ser/sip_router$ scripts/ser_mysql.sh reinstall
MySql password for root:
creating backup database
dumping table content (ser)
dropping table (ser)
creating new structures
creating database ser ...
restoring table content
ERROR 1054 at line 42: Unknown column 'usernamename' in 'field list'
reinstall: restoring table failed
I solved this by commenting out the following line in ser_mysql.sh
# sed "s/[uU][sS][eE][rR]/$USERCOL/g" |
But then thow following error came as next after running the
"fixed" ser_mysql.sh:
ERROR 1054 at line 108: Unknown column 'perms' in 'field list'
This one I circumvented by inserting a line, which does replace all the
strings perms by rpid as follows:
sed "s/[uU][sS][eE][rR]_[iI][dD]/user/g" $tmp_file |
# sed "s/[uU][sS][eE][rR]/$USERCOL/g" |
sed "s/[pP][eE][rR][mM][sS]/rpid/g" |
sed "s/[rR][eE][aA][lL][mM]/domain/g"> ${tmp_file}.2
After running it again I executed the following in the mysql client:
update subscriber set rpid="NULL" where rpid !="NULL"
I hope someone can fix this once...
and that my fix really helps...;-)
cheers,
Bernie

Hi,
I managed to get rid of the Wrong FIFO Interface version. Now I'm getting
these errors on /var/log/messages and in sems debug mod, when making a
call with the same configuration. Is it again due to a problem in
versrion? The the sems is downloaded from ftp site and is
sems_2004_01_04.tar.gz. I tried this with ser downloaded via cvs and the
one from the ftp site. Any ideas?

Hi,
I've tried to test the pa module (ser 0.8.12) in conjunction with the
SCS Client.
The SCS Client appends a special generic param: 'ScsId=ch' at the
From: header in the subscribe message. And the NOTIFY answer from
ser contains this param but omits the semicolon. So the NOTIFY message
will be treated as wrong.
The ser config for SUBSCRIBE method is straight forward:
if (method=="SUBSCRIBE")
{
if (t_newtran())
{
handle_subscription("registrar");
};
}; # subscribe
The ngrep output for this transaction is:
#

For me it seems to be an error in ser. Have anyone an idea for a workaround?

Hello.
There is a mess with 'prefix' argument to 'make install' (as
suggested by INSTALL text) in stable CVS version. SER is installed in
correct place, but is still trying to search ser.cfg in
/usr/local/etc/ser/ by default.
This happens due to the fact that the default value of $prefix
(/usr/local) is used (CFG_DIR = $cfg-target = $prefix/$cfg-dir) during
compilation (when no prefix is given). So, installing to different
location with 'make prefix=xxx install' produces the mess.
Probably, the described issue affects other pieces of software.
Workaround: always use make command with your prefix=xxx argument,
i.e. $ make prefix=/my/prefix all; sudo make prefix=/my/prefix install
Could anybody fix the problem? (At least in INSTALL file.)
...Bye..Dmitry.
Please always CC the list, comments inline:

Why don't you read the documentation first ?, See

This is a known issue with WM, digest realm must be equal to the domain
part of From/To URI, this is not the case when you use IP address.

Hi,
I'm trying to implement voicemail with ser_0.8.12 and sems_0.1.0 on the
same machine. All servers seem to be running alright, but when I dial a
user who's voicemail option is enabled, and is offline, the xlite displays
"trying" for a while and then 408 request timeout.
The logs in /var/log/messages says
Error: ## Wrong FIFO Interface version ##
Any idea about this?
Configurations are as follows.

Hi,
I looked at the archieve and tried to find a solution
for natted clients in a carrier environment. I have to
say I am clear as mud. In our senario, some clients
are behind nat, while others are not. Clients may move
between nat and no-nat. What's the best approach to
rtpproxy/mediaproxy. In rtpproxy's readme, it uses
"search" to find certain client. It has issues to
support other clients. Is nat_uac_test/client_nat_test
sufficient to test either src or dest is behind nat
and should go through media proxy? What if some
clients have stun support? What if some are behind
symmetric NAT and some are not?
Thanks for your help.
Richard
