[Asterisk-Users] unable to enable stutter dialtone

[rkb at i.frys.com]

I'm having problems enabling stutter dialtone for users connected to
channel banks.

Half of our users are on iaxy's and the other half are connecting to
channel banks.  The users on ixay's are getting the stutter dialtone
on new voicemails, but the ones on the channel banks are not. 
Currently, all users are in the default context in the voicemail.conf
file.  I've tried the following 3 methods for the entries in the
zapata.conf file, but none have worked.  The first method is what I
use in the iax.conf file and it's working.

mailbox=1234


mailbox=1234 at default


channel => 49
mailbox=1234 at default
callerid=”foo bar” <1234>


Does anyone know how to fix this issue?
