Just wanted to give you something to consider when you are starting out. Something I didn't consider. This is going to be very country specific. Here in the UK, I've installed several small systems without a dial-9 for an outside line type thing. The outside line prefix is effectively digit zero. (which is preserved and dialled on the outgoing zap lines) The down-side is that you then have to dial the entire 10 or 11 digit number to make a call, even a local call where you would normally drop the 4 or 5 digit STD prefix, but that really isn't a problem now as we've been doing it that way for years on our mobiles, and incoming caller-id is always the full number starting with 0, so we tend to use the full number in the speed dials, especially if the phone uses the speed-dial name+number to identify incoming calls... (Which does irritate me when I'm in some town I don't know very well and ask someone for their phone number and they just give me the local part!) There is an exception for 999, and I still provide the 9 service too for things like 100 (BT operator), and other services like directory enquiries, fault reporting, etc. it's easier to just provide the 9 service too and then advise the punters that's the way it is :) Gordon ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

But what for are single-character extensions reserved ? As others have mentioned the single character extensions are reserved for special extensions in the dialplan, i.e. 's' for start, 't' for timeout, 'i' for invalid, etc. However, the single digit extensions are not reserved, so you can use them if you want. The only problem with using single digit extensions is the reduced flexibility in your dialplan, i.e. things like: 1) no room to expand your number of extensions without having a mix of 1 digit and 2 (or more) digit extensions, 2) having to have a prefix number for dialing an external number, etc. Of course, if you don't have a dialout digit (e.g. '9') then you have limited flexibility also. Since I don't have a dialout digit and I allow both 7 digit (NXX) and 11 digit (1NXXNXX) dialing, I don't have that many options for extensions either (they either have to start with 10, 11 or 0). Right now I'm using three digit extensions starting with 10 and 11 (i.e. 10X and 11X) but I am running out, and am thinking of moving to three digit extensions starting with 0 (i.e. 0XX, except 011 would still work for international dialing). I don't have any use for just 0, since I don't even know what dialing an operator should mean in the context of a mixed PSTN and multi provider VOIP setup (not to mention I haven't called an operator of any type in over 20 years).

It doesn't have to be the default 701-720.

[asterisk-users] Extension Numbering
Hi again, as I wrote before, I'm new to Asterisk. And so, many many new questions pop up . For example: I have here a very small telephony system. We have only 5 (or so) extensions. (4 phones, 1 fax). So I wonder if there is disadvantage if we use only 1 digit extensions (1 for boss, 2 for shop, 4 for the fax ...) I think I can remember something from the Asterisk-TFOT book saying that one must not use 1-digit extension numbers. But I can't remember that very well and can't find it in the book any more Regards, norbert ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Re: [asterisk-users] Extension Numbering
I'm not too sure on that. I don't really know, unless maybe for an IVR and you want a menu of options (which can only be 1 digit) and also dial direct to the extension. That would limit you in that regard. I have a suggestion regarding dial plan. When I first started I saw no reason to have to dial 9 first for outside calls. Because I wanted to be able to dial out from the missed calls list, I chose to eliminate the dial 9 requirement.

But what for are single-character extensions reserved ? There's: a (*) s (start) t (timeout) i (invalid) h (hangup) And maybe others, those come to mind right this second since I use them a lot. They want to be sure they have 21 more possible default available extensions. That's why it's adviced to not use them to prevent trouble with newer versions where your single-character extensions clashes with some default builtin one. For readability it's also better to use descriptive extensions instead of singe character ones. -- Michiel van Baak [EMAIL PROTECTED] http://michiel.vanbaak.eu GnuPG key: http://pgp.mit.edu:11371/pks/lookup?op=getsearch=0x71C946BD Why is it drug addicts and computer afficionados are both called users? ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
