Ringtone issue

[sunspark]

is it possible to choose the ringtone according to the number of the caller?  Here the issue: on 69xx phones we can differentiate the ringtone according to internal / external calls, the problem is that the did number that I call goes into the call director IVR, choice 1 blind transfer to a ring group.  The call is therefore considered internal.  Any idea ?

There's no way to change ring tone based on the number calling.
But I'm thinking, but not sure, there may be a COS change that allows XFERED calls to be presented as external.

hi Ralph,

do you know which cos i have to activate? on the trunk or on the user?
for the moment a call coming from the IVR to a user is considered as an internal call transfer. and I can't distinguish whether it's an internal or external call depending on the ringtone.
