<p style="margin-left:35.4pt">Hi Patrick,<o:p></o:p></p>
<p style="margin-left:35.4pt">Thanks for your reply. I'm aware of the max_branches parameter in the config file, but my understanding from trial and error is that the bounds of the max_branches parameter is set by MAX_BRANCHES_LIMIT in config.h.<o:p></o:p></p>

<p style="margin-left:35.4pt">Hi,<o:p></o:p></p>
<p style="margin-left:35.4pt">I am building a configuration script where for some traffic flows parallel forking will be needed, and in this case I need to go beyond the default max limit of the max amount of branches.<o:p></o:p></p>
<p style="margin-left:35.4pt">Apart from this specific case the traffic load that kamailio will need to handle is very low, let's say just one second here and there with up to 5 concurrent calls at most.<o:p></o:p></p>
<p style="margin-left:35.4pt">This limit is as far as I understand set here: usr/local/src/kamailio-5.6/kamailio/src/core/config.h<o:p></o:p></p>
<p style="margin-left:35.4pt">And the default limit is:<br>
#define MAX_BRANCHES_LIMIT 32 /*!< limit of maximum number of branches per transaction */<o:p></o:p></p>
<p style="margin-left:35.4pt">Here are the questions I have related to this:<o:p></o:p></p>
<p style="margin-left:35.4pt">1) If I increase the value of this constant in config.h, how high is it reasonable to set this value and still have a stable system?<o:p></o:p></p>
<p style="margin-left:35.4pt">2) If I increase MAX_BRANCHES_LIMIT beyond 32, are there also other parameters that needs to be changed for the system to be able to cope, and if so which parameters?<o:p></o:p></p>
