Asterisk is up and working with Cisco SIP phones and a Cisco SIP
gateway.  MOH works.  Inbound/outbound calling works.  This occurs even
with no calls active.

I just can't figure out where this message comes from or how to get
additional detail.  Built with CVS from about a week ago.

Thanx to anyone who can shed some light on this.
