[Asterisk-Users] Transfer directly to voicemail?

[daryl at introspect.net]

Does anyone have a setup (or am I missing a simple thing here) to
transfer a caller directly to someone voicemail?  Example: I receive a
call, the caller wants to speak with x, who I know is not in the office.
Other than transferring them to x's extension, which rings to timeout
and then picks up voicemail, can I transfer right into voicemail?

I am using all SIP phones in my setup (7960s).
Thanks,
Daryl
