OK - that’s reasonable. Of course, your questions below are still pretty basic, so it sounds like you need to do some more research.
The “extension range” is largely in your head.
In your outbound route, there’s a place where you match the destination numbers that will be sent to “this route”. In there, you can put something like “10XX” to send all of the calls to 1000 to 1099 down that route.
Nothing - let the extension numbers fly. Also, make this route an “intracompany route”.
You will need an extension number for every phone. This is the number of the phone. The phones won’t ring without extensions. The extension number is how the phone registers.
I wouldn’t use 2-digit extensions, especially ones that start with ‘0’. As a matter of “best practice”, I found that three- or four-digit numbers are good - they’re short enough to be quickly dialed, but long enough to not be mistaken for control codes for the PBX (commands are usually a * followed by one or two digits).
The outbound Caller ID should always be in the form [“Name” <Number>]
When I set up systems, I usually make the extension CID "Employee Handle" <1000> so that the local calls all get plenty of support. When the call goes outside the organization, I set a “trunk” caller ID in the form "Company Name" <8005551212>
I think ‘the place’ you’re talking about are the dial patterns, I just put 1xxx into the ‘match pattern’ field, hope that’s right.
It seeeeeems to work now =)
I still have a question left, since I don’t know in how far it depends on maybe wrong settings, I won’t create a new topic for now.
I need a softphone and chose Zoiper, but I can’t register a new account, doesn’t matter what I put in the fields.
