-----------------------------------------

Rusty,

Was my previous line of thinking appropriate or am I just out of luck?

Thank you,

> When triggering exitcontext logic inside of the VoiceMail application, calls sent to the local channel cannot transfer.

>      3. Press 0
>      4. Call triggers 'toSvcCenter' dialplan logic
>      5. Transfer function triggered

> I am unable to perform a Transfer() back on the SIP/Asterisk_CLE-00000024 channel.  My call flow requires a SIP REFER in order to remove this server from call flow.  Dial() works, but the upstream server is expecting to produce a REFER to the originating SIP Server as well, and this results in calls being REFER'd back to Asterisk rather than upstream.
