[cisco-voip] SRST Prefix

Gents,

Thanks for the prompt replies.  The 'attendant DN' is configured properly
under the port configuration in CCMAdmin.  Inbound/outbound calls work fine
under normal operations; inbound calls in fallback mode are a problem
though.  

The extension that is configured under the 'attendant DN' is the pilot
number for my Unity 'Auto Attendant' call handler application.  However, in
fallback mode (SRST) I cannot redirect inbound calls to an alternate
extension because the 'attendant DN' (auto attendant) is no longer
available?  

I have tried using the 'Alias' command.  When I enable my call trace (debug
voip ccapi inout) I see the call come into the gateway and connect, but then
nothing happens (dead air).  I even tried using translation profiles to
convert the 'called number', or lack thereof, to a known extension - similar
behaviour to 'Connection Plar' for H.323.  Same 'dead air' results.

Please keep the feedback coming, they're all great ideas.

Best regards,
Colin

For MGCP, you will need to configure "attendant dn" under the port 
configuration in CCMAdmin.
