Hi,
An alternative to the C/Module version would be the following:
# Allow no more than 2 contacts per AOR
modparam("registrar", "max_contacts", 2)
# Order usr-loc entries by the order of registration, not the Q-Value:
modparam("usrloc", "desc_time_order", 1)
# Table holding last selected AOR per record:
modparam("htable", "htable",
"selectedaor=>size=8;autoexpire=7200;")
if(reg_fetch_contacts("location", "$fu", "caller")) {
# Registration found
if($sht(selectedaor=>$fu)!=$null) {
if ($sht(selectedaor=>$fu) == 1) {
$sht(selectedaor=>$fu) = 0;
} else {
$sht(selectedaor=>$fu) = 1;
}
} else {
$sht(selectedaor=>$fu) = 0;
}
# Rewrite URI
$ru = $(ulc(caller=>addr)[$sht(selectedaor=>$fu)]);
# and do whatever you want, with the rest of the info...
}
So long,
Carsten

Thanks Daniel for the suggestions. To make the script manageable, I am
thinking of implementing last option.
Have another flag to "save". May be 0x8?
yes, it is ok.
Perhaps this should have lower priority than 0x4, just in case someone sets
both of them.
We will still use max_contacts = 2 in mod params.
And when the save("location", "0x08") is called, the oldest contact
is
removed and the new contact is
added. This can apply to any number of max_contacts...
Perfect. As said in previous email, this value can be set per registration
right now, with devel version.
Cheers,
Daniel
This way everything else remains the same.

Hi,
Is there a way to set up maximum of 2 active roll over contacts per user?
Currently when I setup max contacts param as 2,
The third one is responding with 503 error for 3rd Register. How can we
remove one of the contacts and replace it with the
new one.
I need it when the device is switching over from Wifi to 3G and back. or
Wifi network to Wifi network switching.
the master branch support setting number of contacts per registration, but
it is the old fashion of rejecting new contacts.
Some ideas coming in my mind, not sure if all get to a proper solution:
- play with two tables for usrloc, like location1 and location2, each with
save(...) last registration and you do round robing with the registration
(use htable to keep which location table to use next). Then do
lookup/append_branch over the table one, revert the uri and do lookup over
the second table -- combine these operations as you need
- use database mode only and then sqlops to remove entries that are no
longer useful for you. defining location table in memory (possible with
mysql), gives you good performances
Of course, an extension to c code to have such functionality would be
another option, contributions will be accepted as usual.
Cheers,
Daniel
