[asterisk-users] Disable the flash hook hold capability on a SIP-to-SIP or SIP-to-ZAP call?

[Ricardo Martins]

Hi all. I´m trying to disable this simple thing: I dont want an user to 
put a call in hold pressing hook (or flash button). I tryied disabling 
all the transfer/forward/threeway... capabilities of my zapata.conf and 
the user is still allowed to put the call on hold no matter if its 
calling to a SIP-peer or a ZAP-channel.

I found a message with a similar issue: --

--  that points to a patch from early 2004: --

Do anybody has a clue?
