[Freeswitch-users] Best Practice - * Codes on some IP Phones

[William Colls]

I am working with a Grandstream HT704 ATA device which has number 
special functions built in eg Do Not Disturb, Suppress Outgoing Caller 
ID Number, Enable/Disable Call waiting, - more than 20 in all. 
Unfortunately, one of the codes is *98 which pays back the extension 
number. In order for *98 to work for e-mail, I must disable all the call 
features.

So my question- Is it generally considered best practice to disable the 
functionality on all phones, and provide it through the dial plan so 
that the codes will be consistent for all phones in the system, or let 
the phones provide the features, even if they may vary from phone to phone?

Thanks for your time.

William.
