This has been fixed and will be included in the next out.
If you can't wait then here is a patch for you..
Using your favourite editor load the following template...
/etc/e-smith/templates/etc/asterisk/extensions.conf/90-presets
At or near line 208 find
exten => _*90X.,1,agi(selintra,*22*$\{EXTEN:3\})
Replace it with
exten => _*90XX.,1,agi(selintra,*22*$\{EXTEN:3\})
save it back and issue a commit from Globals Panel.
That should do it.
Kind Regards
S
