After moving to 30, just check the usage of the shm memory, as TM
will start using more (the branches are statically part of the
transactions, so the transactions will become larger with 30
branches).<br>

<p>Thanks, i will try raising max_branches to allow the use of
more gateways.</p>
<br>
<p>Yeah i know it seems to be unusual to "try" so many gateways,
but the setup works with a lot of smaller instances which are
immediately rejecting calls when full to allow a failover to
the next instances. Load balancing would be a better solution,
but is not feasible in my scenario.</p>
<p><br>
</p>
<p>Also it seems that tm module additionally has a limit of 30
branches. Anyway it should be enough even for me. :)</p>

<div><tt>Hi Max,<br>
<br>
Yes, a transaction cannot have more than 12 branches used. But
this does not limit how many GWs you can put in Dynamic
Routing - you can put as many as you want on DR, but of course
only 12 will be tried. But this depends a lot on the GW
selection algorithm (with wights, with carriers, etc). To
actually end up trying 12 gw for a call is a very rare case, I
would say :)<br>
<br>
