>          Issue Type: Bug
>      Security Level: None
>          Components: Channels/chan_dahdi
>    Affects Versions: 18.11.0
>            Reporter: N A

> In chan_dahdi.conf, we have:
> {noformat}
> ; Logical groups can be assigned to allow outgoing roll-over.  Groups range
> ; from 0 to 63, and multiple groups can be specified. By default the
> ; channel is not a member of any group.
> {noformat}
> However, there is a typo in chan_dahdi.c:
> {noformat}
> /*! Round robin search locations. */
> static struct dahdi_pvt *round_robin[32];
> {noformat}
> This actually needs to be 64, or otherwise only  groups 0-31 work correctly with round robin, and 32+ don't work with round robin but work with "G" for instance.
> This fixes this issue so that they are both consistent with allowing 64 groups (0-63).
