hi I have an avpops question
I have an avp object of boolean type called forwardcalls. My question is how do I check if a specific user has this enabled or not? I have the following logic:
if (avp_db_load("$ruri/username", "s:callfwd")) {
xlog("L_ERR", "call forward [%Tf] method <%rm> r-uri <%ru>\n");
if ( avp_check("forwarded_calls", "eq/0/gi" )) {
log(1, "forward calls is disabled!\n\n");
break;
} else {
setflag(22);
avp_pushto("$ruri", "s:callfwd");
route(6);
break;
}
};
I think my avp_check is wrong. Any ideas?
I want to modify my ser.cfg so that if a user dials
*5(then their iConnectHere username, password and the
pstn phone number they want to call), the sip server
will forward to information to iConnectHere, where the
call is sent to the pstn phone number.
Ex: If a user's iConnectHere username is 12345678 and
their password is 1122 and they want to call the pstn
number 9-999-999-9999, they will dial
*512345678112299999999999 to call the desired pstn
telephone number. How can I modify my ser.cfg to
include this? (If you can, please include the code I
can insert into ser.cfg or a sample ser.cfg file). Thanks.

One quick addition, I'm using the latest versions of SER and mediaproxy
that I could find:
ser 0.9.4 and mediaproxy 1.4.2.
Original problem follows:
I have been trying to configure SER w/MediaProxy module/server to be a
drop in NAT solution in front of asterisk. With the twist that I want
to have asterisk continue acting as a registrar rather than SER.
Outbound calls from natted clients works perfectly currently. The
problem I'm having is with SER passing the REGISTERS through to
asterisk. SER/MP isn't rewriting the address in the packets to go back
through SER, but instead sets it to be the NAT'd IP of the client.
So, when asterisk receives a call, and tries to send it to the external
nat'd IP of the client, there is no open session from asterisk, so the
firewall denies the request.
What I need to happen, is for SER/MP to rewrite the packet with it's own
IP, so that asterisk sends it back to SER, and SER forwards it back down
to the client, from a source IP which has an open firewall session.
Any help would be greatly appreciated, hopefully it's just a matter of
me having an extraneous function call somewhere, or being ignorant of
the right function to use.
Or, in ascii diagram form:
NAT_IP client --- EXTERNAL_FW_IP ----- SER_IP ----- ASTERISK
SER is giving asterisk the EXTERNAL_FW_IP for Registers, and I want it
to give Asterisk the SER IP.
Something that would make SER rewrite *all* register packets to it's own
IP would even work, since clients that don't need NAT won't be sent to
SER in the first place.
My ser.cfg and mediaproxy.ini follow. Lemme know if you need any more
info from me. And extra thanks to anyone who has taken the time reading
this, I truly appreciate it.

Subject: [Serusers] Multiple backup routes
Hi,
if in a system i need to have more that one PSTN gateway to try for a
destination in sequential order (note that gateways are dinamyc and may
change call by call) and the order is important because them can be
ordered for costs of the call from the less cost to the higher.
There is a way for example to append all of them as branch and try them
in sequence?? Otherwise i have to process them in a separate route block
and have a temporary table in a database where take next gateways to try
for that destination and that specific call, removing every cycle the
used gateway.
Any ideas to accomplish it in one step and let SER manage it??
Thanks,
Bye,
Marcello

Hello everyone!
Im changing platforms and I have problem compiling ser for my new arch. I
now have em64t servers with rh es.
Actually the problem is compiling ser with mysql module.
- Mysql em64t rpm installed from mysql site.
- ser 0.9.4 sourcetree.
When i compile everything works ok. But making mysql module fails. It
complains about some relocation problem between 32 and 64 bit libs. I cant
understand this since mysql is em64 version and so is ser. Off course bin
version of ser does not work too. Here mysql.o complains about not finding
mysqlclient.so, allthough it is there.. :-/ Anyone had luck with this?
Probably some makefile tweaking to get it to use correct libs or something
since this sweet rh has lib64 and some lib stuff cinfusing both me and ld
:-)
Would appriciate help!
Cheers..

Hello
I'm struggling to understand how all the bits of a VOIP system fit together and
whether OpenSer can act as a UA and authenticate to a remote proxy.
What I want to achieve is this. Incoming SIP calls are first routed to a SIP
phone on the network. If this is unavailable, the call is then redirected to
another proxy of a voip service provider with whom I have an accout, whence it
should be routed to my mobile phone. I guess I can rewrite the call URI to
mymobilenumber(a)proxy.voipprovider.tld, but I will need to authenticate to the
proxy to authorise the call and have it charged to me.
Can I do this with SER, or do I need something else (Asterix?) for this sort of
function?
