Hi,

If you need to see channel list often, and there are lot of clients
requesting the same over-and-over, i could suggest trying out this
patch

http://ftp.iq-labs.net/realtime_channels/asterisk_realtime_channels-1.4.19.patch

Currently i have it for 1.4 version, but if you're interested i could
scrape it out also from my 1.6-patchset.

It would keep up-to-date list of channels in database - a little
additional load upon creating/manipulating/destroying channel, however
it unloads from tons of requests to Asterisk. Also implementing this
did relieved us from deadlocks/crashes when "show channels concise"
tried to access locked channel, or one with broken pointer.

This probably is never going to Asterisk, as similar queue status
patch got rejected, but i'm keeping it up for my own use :)

Regards,
Atis
