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>

<p>I think i got it, default limit is 12 branches in config.h. Which corresponds to my limit of 12 gateways, I will try and report back. :)<br>

<div style="margin-top:0; margin-bottom:0">I've never noticed this until i came across it recently. I got a weird issue with drouting, it turned out that even though the gatewaylist ("carrier") contains a total of 20 gateways, only 12 are being used. (all gateways
got the same weight)</div>

<div style="margin-top:0; margin-bottom:0">Is there an internal limitation for the number of gateways? I know there is a limitation due to the database scheme, and there is also DR_MAX_GWLIST in the drouting.c module.<br>
