When you are updating the documentation, I would suggest to mention one
more thing:
Using $to for any AVP operations might be a security hole, because To header
field it not used in message processing and might not be related to the the
real callee whose SIP URI is in the Request-URI.
For example in the following message:
INVITE sip:george.w.bush@whitehouse.gov SIP/2.0
To: sip:john.kerry@whitehouse.gov
$to based avp_db_load would load AVPs for someone else than the message
recipient.

Hi Jiri,
thanks for you documentation overview. Yes indeed, there is a small
typing error. All module functions takes the parameters as quoted
string. AFAIK only couple of core function breaks this rule.
I will add the " as soon as possible and regenerate the documentation.
Again, thanks for the report.
Best regards,
Marian Dumitru

Nice.
I'm wondering how the following line is supposed to be executed:
if (!(avp_db_load($ruri/domain,"s:t_ips/ips")
I mean -- how is $uri/domain interpreted? Or is it just missing "
in the documented script version that confuses me?
Thanks,

http://lists.iptel.org/mailman/listinfo/serusers Hi Andreas,
you can implement GW failover by doing serial fork using AVPOPS module.
Pleas take a look at example number 4 - Serial forking:
http://www.voice-system.ro/docs/avpops/
You can store all GW IPs in database and load them via avp_db_load().
If you don't want to hardcode even your first GW IP and to rely only on
the IP list from AVPs, be sure to push the fist AVP value into RURI in
main route before first sending to GW.
Unfortunately, this approach doesn't offer load-balancing
Best regards,
Marian Dumitru

Hi all,
Since SER does not provide DNS SRV failover capability, how do you
perform failover for your PSTN gateways?
I currently think about some sort of load balancing with exec_dset()
which looks up a gateway in a mysql db and give it 10 tries to find a
gateway (SER is running on my.domain:5060)
route
{
if (!mf_process_maxfwd_header("10"))
{
sl_send_reply("483", "Too many hops");
break;
}
<snip>
exec_dset("/my/sipgw-balancing-script"); # returns a random GW
t_on_failure("1");
t_relay();
<snip>
}
failure_route[1]
{
if(t_check_status("503")
{
rewritehostport("my.domain:5060"); # peform loop
append_branch();
t_relay();
}
}
Is this good practice? Any other ideas/optimizations?
Cheers,
Andy
