Good morning.

I checked the logs (many times) and couldn't find any incidence of incoming
registrations failing.  That suggests that the registrations weren't making
it to the server!

Well I discovered the culprit.  I use a Juniper Netscreen SSG-5 firewall to
get "outside", and the servers connect to it to get to the rest of the LAN
(a very expensive Ethernet switch!)  Now even though all the phones were
inside the trusted environement, and even though SipXecs ran fine as a
registrar and voicemail server with the Juniper, the conferencing
application resulted in blocked registrations.

I turned off the SIP ALG (application layer gateway) function within the
security/alg menu and everything works fine now.

Thanks for the help with the log files.

Regards,

Keith
