Hello Olivier
Since we originally agreed to include your tones, our policy on Asterisk has changed. We will not modify Asterisk in any way. If you wish to create your own template for Belgium then this is fine, but we do not want to maintain it for you. If Digium produce an Asterisk release with Belgium incuded then we will support it but otherwise not.
I know this seems harsh, but we will no longer spend time supporting non-standard (i.e. - non-ATrpms) releases of Asterisk itself unless we have absolutely no choice.
If you wish to modify your version of SAIL to support 'be' as an option then you can find the country values matrix at, or around, line 474 in /etc/e-smith/web/functions/sarkglobals.
It's very easy to add and it saves us a lot of work if we don't have to support non-standard release sets.
Please accept our apologies, but we are only a few so we try to keep our upstream maintenance overhead to a minimum.
Kind Regards
S
