[cisco-voip] Issues with some calls into unity after user enters *

[Nathan Reeves]

Seeing an issue where calls are passed over to Unity and the greeting
message is played.  When the users presses * to drop to the sign in
process the call gets dropped.

I've checked the call handler, and all looks good.  When calling the
unity pilot from a phone internally, I can press *.  When calling in
from some gateways, pressing * works.  But from one gateway it
doesn't.

Anyone got any ideas where to start troubleshooting?
