[OpenSIPS-Users] Multiple re-registrations in location table

[Nikitah Bobhate]

Hello,

I am in the process of upgrading our version of OpenSIPS from version 1.6.2
to version 1.8.2 and am facing a bit of a problem. I have noticed that
re-registrations sent from a UA are saved as NEW entries in the location table.
Previously in OpenSIPS 1.6.2, it would overwrite the previous location entry for
the same agent. As an example, the following user's initial registration is saved
to the location table (first entry in the example below). The user is registering
over TCP. After about 2 minutes the UA (Linphone in this example) sends a
re-register (second entry in the example below). Only the cseq and expires fields
are different between the entries. This continues for however long the UA is on
(if I exit Linphone, a deregister is sent). Note the table example only shows a few fields.

Is this behavior correct? Should OpenSIPS be adding re-registers as new
entries into the location table? Is there a way I can get the newer re-registers
to replace the older entries?

I have the following in my OpenSIPS config file:

modparam("registrar", "max_contacts", 1)
...
...
if (is_method("REGISTER")) {
...
    if (!save("location","f"))
        sl_reply_error();
...
}


Thanks,
