Hi,
I am under training of Networking, and my project for final exams is VOIP. I read about SER and downloaded 0.8.12 version. I have linux 9 and would like to give demo on the same system. In our institute we have two IP phones (Hardware/Hard Phones).
Please help me in installing the same. As I am new for this. I would appreciate if I can get step wise instruction for the same.
Thanks in advance.

I think you can use jan's avp module to make something like that happen
.-) tough. you would need to forward to different users..

Hi ,I am a student studying in VoIP and implementing my theory in SER.
I try to access mysql database to get some information, but have a problem aboout paramaters of exe_msg.
My goal is :count the number of contact addresses that certain user registered, and take
this is my solution:
exec_msg(' Count="select count(contact) from location where username=\"$SIP_HF_CONTACT\" "'
CountResult=`mysql -user -pheslo -e "$Count" ser`;
')
What is the result of "CountResult" ?
I suppose originally that it will be the the number of the query, but it seems not.........
If not, what it will be? How can I get my answer what I want to get ?
Looking for all of the documents, I still can't find the information about how to access databases with exec_msg function.
Hoping someone can give me some advises ^^.
Thannks in advance.

Hi,
Thanks for the great work on avpops. It is really an existing module which
opens lots of opportunities. I read some document, just want to make sure I
understood it correctly...
. Every avp type should be saved in a different table. For example, I have
two caller id settings for each subscriber, inter-domain and intra-domain. I
should use one table for each setting. To load them, should I just use
"avp_db_load" with their respective table name? Another question is, since
the table name is optional, what happens if it is not given? When is it
loading from?
. It looks like that one avp can have multiple values. For example, you can
have avp_write("sip:addr1@test.com", "i:2") and
avp_write("sip:addr2@test.com", "i:2"). So avp name i:2 has both values.
. If an avp has multiple values, I can use avp_pushto() to do a parallel
forking.
. Can I use an avp for the existing function? For example, I'd like to use
different caller id inside "Remote-Party-ID". If I already load avp name
i:10 with the right caller id, can I use append_hf() to add a new field with
the avp?
. In the example of Trusted IPs, what if I don't care about any username or
domain? For example, I have a PSTN gateway shared by all domains. Should I
put "" in uuid, username and domain columns? Then what do I put in source
for avp_db_load()? It seems that source can only take either username or
domain or both. Maybe define a uuid value and associate all gateways with
the same uuid.
Thanks again for the great work,
Richard
Hi ..I have a problem with aliases....when I set an alias my serctl

hi
we have 1 ser + 1 asterisk on different computers
we want to forward incoming calls from the server with fixed prefix (eg 00) to asterisk.
i tried different solutions but how is the connection logic between ser and asterisk? should i have a registered user in asterisk which collects all the traffic coming from ser or not? how can i setup the ser and asterisk to have then "talking"?
thnx in advance for help
Graziano
By setting the environment variable LOCALBASE and the make variable
"prefix", the install of ser can be *almost* completely in user disk
space. The exception I encountered is in serctl and sc scripts. They
have lines like
PID_FILE=/var/run/ser.pid
which is out of bounds for a /home user.
Perhaps this value could be read from the ser.cfg file. Alternatively
an environment variable like SER_PID_FILE could introduced and PID_FILE
could pick it up if set.
Also "serctl restart" fails on an error if ser is not running. The way
others servers, eg apache, work is for restart to mean
"if (alive) kill; start". That way the end point of "restart" is always
a running server with a newly read configuration or a server that failed
to start because of configuration failure. It does not depend upon the
previous state. The combination "stop" followed by "start" already gives
you a version of "restart" that fails on error if the server is not up.
By running ser directly both problems can be worked around.
John.
Hello.
It works for me. In fact this is a pending question that i have. i
found this configuration looking for another problem solution in the mailing
list. The "domaintables" file is a flat file like this.
domain
your.domain.com
It solves my problem. Con someone tell me if this is ok? I used this
configuration trying to avoid the use of sql data base.
Thanks in advance.
Ricardo.

Does it work with a flat file?

Hello list
Beside the BYE problem that i post in a past mail, i detected
another weird behaivor of SER. When i made a call from a registered
endpoint (64.76.148.242) to a PSTN-number through a PSTN-Gateway. The
destination devices keep ringing even if i send a CANCEL message. I don't
understand why. Here is the debug
