> But the name of the header changes for each transaction/dialog?
Yes, that's intended - I do not want to store AVPs in
a contact-specific way (otherwise, if I use i:11 from
Bogdan's example, the script overwrites previous values
on a second call from the same terminal, nonregarding
that the first call might not yet be closed) but in a
call-specific manner, i.e. the attribute name (string)
identifies the call-id that the value stored in the AVP
belongs to.
Like stated in a previous answer - it's about creating
a P-Charging-Vector according to RFC 3455 in the core
and inserting it into all forward and reply messages.
The AVP name should be created and last exactly for the
duration of a SIP transaction. The timestamp is required
to guarantee the uniqueness of the value (must not be
re-used for a duration of at least one month).
A distinct AVP name is required for any call (identified
by a distinct call id).

HI HO!
Correct me if I'm wrong, but it seems you trying to use the AVPops to capture a time stamp of the very first INVITE of a transaction? To get this same information, I've used the acc module.
For billing and user call logging purposes, I needed this info and have used:
acc_db_request("CallStart", "acc");
in openser.cfg.
This logs a record to the acc table containing the sip_callid, timestamps, and in "sip_status" is the string "CallStart". I then had various scripts parse acc to the format I needed for the end user.
Hope this helps,
jj

Hello,
Im configuring Openser with LCR module and Im having an extrange
behavior, I have 2 gateways, GW1(preference1) and GW2(preference2),
GW1(pref.1)
/ \
ClientA --> OpenSer --> Client B
\ GW2 (pref.2) /
When I call from Client A to Client B using GW1, all works fine, its the
same when hang up Client B or Client A, but when GW1 fail(I provoke it
changing codec) and use failure route (GW 2) then if Client A hang up all
works fine, but the problem is when is Client B who hang up, its like a new
conversation, GW 2 send BYE to openser and Openser just send "503 Service
Not avilable - No gateways" to GW2, but doesnt send nothing to ClientA, any
idea ????
Thx in advance
this is my basic configuration( I have attached full config file):
route{
if (!method=="REGISTER") {
record_route();
};
if (loose_route()) {
append_hf("P-hint: rr-enforced\r\n");
route(1);
};
if (!uri==myself) {
append_hf("P-hint: outbound\r\n");
route(1);
};
if (uri==myself) {
if (method=="REGISTER") {
save("location");
exit;
};
if (method=="INVITE") {
if (!lookup("location")) {
if (!load_gws()) {
sl_send_reply("500", "Server Internal Error
- Cannot load gateways");
return;
};
};
if (!next_gw()) {
sl_send_reply("503", "Service not available - No gateways");
return;
};
};
};
};
t_on_failure("1");
route(1);
}
route[1] {
if (!t_relay()) {
sl_send_reply("666","t_relay fallido");
return;
};
exit;
}
failure_route[1] {
if (!next_gw()) {
t_reply("503", "Service not available - No gateways 1");
return;
};
if (!t_relay()) {
t_reply("666","t_relay fallido");
return;
};
}
Is there any useful information ANYWHERE about avp's? I mean, don't take this the wrong way, but I've never had so much trouble interpreting/finding documentation on a subject. I can't even find out how to print the value of an avp with xlog. Is this ACTUALLY DOCUMENTED anywhere? I finally found an example somewhere from a newsgroup posting and used:
xlog ("L_INFO","$avp($foo)");
but openser complains with:
Dec 15 13:21:01 bil-pdev-3 openser[24718]: ERROR:xl_parse_name: unknow avp alias"foo"
Dec 15 13:21:01 bil-pdev-3 openser[24718]: XLOG:xdbg_fixup: ERROR: wrong format[$avp($foo)]!

Hi Doug,
use avp_printf() or avp_subst() to process the content of an avp - this
function covers the assigning operation.

I'm sending a lot of info to syslog with xlog(), and with multiple threads (processes?) and multiple calls running, all the output is out of sequence. As a result, I'd like to prefix the debug output with the call-id. The call-id however is very long and I'd like to cut it down and only display a portion of it.

Klaus,
All calls are going through OpenSER from the phones. However, they don't go BACK to OpenSER. Asterisk terminates the call. Putting all calls BACK through OpenSER would be a nightmare. It would make a lot of Asterisk features such as ACD Queues, MeetMe Conferencing etc very hard to manage. I'm not even sure if they would work.
Doug.

I can't explain it, but I do not like the idea replicating with failure
routes ...
IMO it would be better to modify t_replicate to allow to replicate to
moultiple instances.
Would i be possible to route all calls via openser? Then you do not need
the location info in the Asterisks.

It can't even perform a user defined action when a phone registers... doesn't leave us with many options. Right now, using OpenSER to replicate (forward,t_relay,t_replicate whatever) seems to be working ok. Do you have any reason to believe it wouldn't scale up well?

So... using an example I found, if I have something like this...
avp_printf("i:20", "This is a $rm request with the call-id $hdr(call-id)");
how do I print the value "i:20"? or whatever the heck that means....?
