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 branches per transaction .

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 the error .
 INFO:tm:mod_init: TM - initializing...

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

                    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.
