It's possible -- you'd have something like [incoming] exten => s,1,Wait(20) exten => s,2,Answer exten => s,3,Voicemail And that would be your only context. If you want to get IVR'ish when checking your incoming messages, you can write another context for that. The problem is that there's really no telling *what* asterisk will do if you pick up the phone *while* it's recording a message -- unlike an answering machine, it likely won't hang up by itself. I would consider running the PSTN line *through* asterisk, using an FXO and an FXS interface (Sipura 3000 comes to mind). It's some extra money, but it provides you additional functionality such as telemarketer handling, DND modes, or even call-recording. > That leaves another problem - retrieving the messages.

Do I have this right? Correct -- an easy out to this option is of course EMAIL :) Asterisk's voicemail can be configured to send an email for each message received, including a sound-file attachment. Or, the option of running your PSTN line through * would allow you to check voicemail from any extension phone. > 2.

As for 7 and 11 digit numbers, I have something like that in place -- my "wife-friendly" PBX only has the requirement of dialing all numbers as 11 digit numbers. The dial-plan is fairly simple as such -- "1"+10 digits is always an outgoing call; "2"+2 digits is an extension; "6"+2 digits is speed-dial, etc. *123 is voicemail here. You could implement the 7-digit dialing using your own handy-dandy list of local prefixes, but I recommend against that. Using mandatory 11-digit dialing makes returning calls (from caller-id) easier, and you don't have to change your speed-dials when you move, or your area code changes -- and the latter seems to happen more often than the former. Three digit numbers are easy as well -- 911 goes through directly, 411, is ignored because it's ridiculously expensive, and 311 isn't really all that interesting. I'm pretty sure I posted parts of my dialplan last year, but don't have access to it right this minute. _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
