Hi there
Thanks for your input. I'll try to deal with your questions in order
V4 is general release on the SARK200 embedded platform. It's doing very well in production and seems pretty rock solid. V4 is also in production at customer sites on both SME8 and Debian Wheezy. It is performing well and can be considered production ready.
Dynamic-proxy-ignore fixed an issue in V2.0 on SME, or at least, stuck a band-aid on it. The problem was architecturally fixed in V3 so the ignore list was no longer needed. V4 dynamic proxy is much the same as V3 so no list.
You cannot specify a recording path in V3/V4. The recordings end up in /var/spool/asterisk/monout. You can do what you wish with them thereafter, move them, age them, whatever. MONITORSTAGE still exists but it always points to /var/spool/asterisk/monstage. The recording mover will periodically move any amalgamated recordings from monstage to monout.
V4 is one dialplan per COS entry so you'll need multiple COS lines.
V4 makes extensive use of AJAX interaction with the server. Any front-panel field rendered in blue can be double-clicked and changed in place. The App description field is an AJAX field. Simply double click it to change it and you will be presented with an edit box.
In the earlier V4 releases we did indeed enforce strict alphanumeric but it was relaxed in later releases to include underscores. Which release do you have installed?
SAIL does not use AEL. You can safely remove it from the Asterisk config as far as SAIL is concerned.
Kind Regards
