Hi Patrick,

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.

Hello

there is already max_branches parameter you can set in config file.

Hi,

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.

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.

This limit is as far as I understand set here: usr/local/src/kamailio-5.6/kamailio/src/core/config.h

And the default limit is:
#define MAX_BRANCHES_LIMIT              32      /*!< limit of maximum number of branches per transaction */

Here are the questions I have related to this:

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?

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?

Regards,
Lars
