[OpenSER-Users] SIP forking - address a certain client on Openser 1.2

[Peter P GMX]

Hi,

we would like to anable the client to register from 2 IP addresses but 
the latest register shall be used for the invite message.
But the problem is - how to tell OpenSER?

As I have read in the documnetation there are actually 2 Parameters 
which handles this processing
        modparam("registrar", "max_contacts", 2)
set the number of parallel registers to 2 (forking)

        modparam("registrar", "append_branches", 1)
delivers to all registered branches

        modparam("registrar", "append_branches", 0)
delivers only to 1 registered branch
But - which one??

In the doumentation there is explained that one can set the q-value. As 
the SIP client doesn't know, how many registers already exist he can not 
set a dedicated q-value.

If I manually change the q-values in the database (table location) there 
is no change in the behaviour. I changed q value from -2 -1 to 0 and 1 
and 2. no change. I could not determine, which rule applies, so I played 
with the other parameters:

§         id

§         q (as above)

§         expires

§         last_modified

No change. I can not see, that if I set one of the values to a higher or 
a lower value as the second register, it affects the behaviour of 
Openser to call a certain SIP client.

Am I think wrong or what can I do to?
