Hi!
It looks like I still have to learn a lot to understand ser, so maybe
someone can help me:
Following scenario: IP-IP with reINVITE (call hold). I authenticate all
INVITEs, also reINVITEs.
The call setup works fine:
UA1 Proxy UA2
| -INVITE w/o cred ->| |
| <--- 407 ---- | |
| ---- ACK ---> | |
The ACK is processed and caught by ser automagically without entering
the routing script. I guess this is done by the stateless processing
because of the debug message:
Aug 14 22:34:47 sip1 /usr/sbin/ser[25694]: DEBUG: sl_filter_ACK : local
ACK found -> dropping it!
Then INVITE with credentials:
UA1 Proxy UA2
| --INVITE w cred -> | |
| | ---- INVITE ----> |
<- ...100, 180 ... --
| | <--- 200 OK --- |
| <--- 200 OK ----- | |
| ----- ACK ----> | |
| | ----- ACK ----> |
The ACK will be forwarded correct.
Now the problem: A reINVITE will be sent to the proxy, and the proxy ask
for credentials. This time, the ACK want be catched by ser and enters
the routing script, and therefore will be forwarded to UA2 (which should
not!).
UA1 Proxy UA2
|-reINVITE w/o cred->| |
| <--- 407 ---- | |
| ---- ACK ---> | |
| | ---- ACK ---> |
How can I configure ser to also handle this ACK automagically?
regards,
Klaus
Hi,
I have a problem about 487 retransmit...
After caller get a 18x from ser proxy, we cancel the call, we could see caller UA send a CANCEL message and get a 487 message from proxy.
UA get 487 message then reply a ACK.. but proxy still send next 487 again and again.
We check called party, no such problem, only one 487 received.
Could anyone give me a hint?
best regard
Kaiser
Dear sir/madam,
I am installing the Mediaproxy SER module on the SER but I am afraid I
cannot the follow the procedure closely.
I am trying to locate the "sip_router" directory on the SER. Since I cannot
locate this directory I am not able to carry forward the upcoming steps.
I am just wondering whether you can suggest where the "sip_router" is.
Thanks

Installation of mediaproxy SER module
-------------------------------------
For CVS:
cd sip_router
cvs update -Pd
#check that you have the modules/mediaproxy directory
make clean # clean old files in case you haven't updated cvs for a long time
make
make install
For stable tree:
copy the directory modules/mediaproxy from development tree
and run a make clean inside it. then recompile the module issuing "make" in
that directory. Copy the module mediaproxy.so to /usr/lib/ser/modules/ser/
For both cases, copy the 2 files listing asymmetric clients from
modules/mediaproxy/config to /etc/ser/
To configure the mediaproxy module in the ser.cfg file please check the
Readme included with the mediaproxy module (available in the SER
modules/mediaproxy directory). Also checkthe example ser.cfg file included
there too.

when I try to a call, it appear this problem
and I install ser-0.8.12 and sems(cvs)
I can't find ans_machine in my server.
how to solve it.
thanks.

Greetings once again all,
Thanks so much for your help on my previous silly errors. I have again met
up with one. I'm trying to have SEMS email users their voice mail. IF the
user is offline, it works very well, however, if the user is online, it
fails.
>From the logs I see that when the user is offline it is emailing them from
"voicemail(a)mysipserver.com" but when the user is online, it tries to mail
them from "voicemail@<users_public_ip>"
The domain in the subscriber table if MySQL is set to the correct domain,
but the contact field in the location table is set to
<user_phone_number>@<user_public_ip> if that makes a difference.
Thanks in advance for your help.
Cheers,
C.
Hello all,
I am having some problems with does_uri_exist. I am getting error "find_export: <does_uri_exist> not found"
I have loaded both uri and uri_db
I have also tried to use the sample config ser.cfg.m4 and my own config which contains the function but his fails with same error.
I am using cvs head 22-juli 2004.
I have authdb running and am getting things in and out of the mysql database.
any ideas ?
Arne.
I compiled from source but acc.so can not find libradiusclient.so.0 and
fails with the message below. However, I do have radius client installed
and actually I ended up copying libradiusclient.so to
/usr/local/lib/ser/modules folder.
I guess I need to know if there is hard coded reference to the location of
the libradiusclient.so in SER which I must change to make it work.
Thanks and here is the message:

At first it seemed like a really good idea then the more I looked at real
world records I realized that to generate a bill for a customer would
require quite bit of work on MySQL's part to match up the INVITE's and the
BYE's and then calc the difference in the times. This causes a bit of a
problem for me because I like my customers to be able to see their CDR
records live. Which really isn't much unless you look at it from a 100,000
user perspective. I would either have to beat up my SQL server every time
they look at their records (or my customer service employees look at them or
even when the biller generates their bill) or run a cron job that runs every
so often to convert the data to a single record with a start time and a
duration and store it in another table. The cron idea isn't too efficient
because of wasting disk space and rewriting a lot of the same data twice.
This then leads me to ask why the SER acc module wasn't setup to generate an
initial start record identical to the INVITE message that it already does
that would be marked as "in progress"? Then when a BYE is received with a
matching Call-ID you find the original INVITE record, change its status to
"done" and populate a duration field. Any ideas why this can't be done
without affecting SER's scalability? :)
Thanks!
