Re: [OpenSIPS-Users] Wrong Contact in location table

Hi, Dragomir!

This is something that I noticed from the first email you have sent -the fix_nated_register() function is not called, or does not workproperly. Can you also print the avp you are setting in thereceived_avp[1]. Also, call script trace for the reply too.

Hi,

Thanks for your email.

Here is part of my location table:

Why "received" field is blank?
Where could be the problem?

    Hi, Dragomir!

    If you simply do fix_nated_register() on the REGISTER messages,
    all these will be sorted out. Moreover, it's actually not correct
    to change the contact of the user, because in the SIP message it
    might expect to have exactly what he sent.
    When using fix_nated_register(), there is another field (called
    Received) that stores the actual IP and port where the REGISTER
    came from, and when an invite comes in, it is automatically set by
    the lookup() function in the DST uri, without changing the contact
    (the contact may still be private).

    So simply calling fix_nated_register() should fix this issue for
    all scenarios.
    I initially though that you were using the Contact from something
    else and you really need that value there.

    Hi,

    Why I need the real IP and port in location table?

    Now I make only outgoing call. Everything works fine on the
    following scenario.:
    User -----> Opensips ------> ITSP

    If I not have real IP in location table incoming calls not be
    implemented.
    ITSP ----> Opensips ---->?

    Opensips get IP from location table and try to send call. But in
    location table have not real IP.
    I see how the Opensips try to send call to 192.168.2.34.

    This is the main problem.

        Unfortunately I just realised that you cannot change the
        Contact header for this scenario.
        And to be honest I don't really understand why you are trying
        to change it - if you need the real IP and port, you can take
        them from the received field.

        Here is the replacement contact:

        How to stop replacing contact from 188.23.232.10:1043
        <http://188.23.232.10:1043> to 192.168.22.138:5062
        <http://192.168.22.138:5062> ?
