I don't think it is working fine, it's probably just that you don't hit the 30 limit. We strongly suggest you to keep an upper limit of 30, otherwise you might experience unexpected behavior.

Is there any reason of doing so .

I have tried to modify this value to 500 in opensips-1.11 and its working fine for me .

Is a limitation of opensips-2.2 .

    Hi Sasmita,

    Currently, it seems that the MAX_BRANCHES is capped at 30. Higher
    values will prevent OpenSIPS from starting.

    I am using opensips-2.2 . I wanted to increase the maximun number

    I have changed the config.h file  " #defineMAX_BRANCHES12 " , I
    increased that to 250 .
    After installing again I am getting error in tm module . Below is

        Are you compiling the module separately? Can you double check
        you are actually installing the new binary and modules after

                        Hi, Sasmita!

                        By default OpenSIPS can fork up to 12 branches
            - are you
                        using more than 12 registered SIP clients for
            the same
                        username? If you are not using more than 12
            registrations
                        for the same user, than you might have an
            issue in your
                        config/setup.
                        If this is the expected scenario and you
            really want to
                        increase the number of branches, you'll have
            to change the
                        MAX_BRANCHES define in config.h[1] and
            re-compile opensips
                        with this new value.
