Default Asterisk post dialling delay

I've set up my trixbox using freepbx. I've allocated the range 5XX for
internal extensions. I don't have any local numbers starting with 5 so I
would like internal calls to route as soon as the last digit is dialled. At
the moment I have to either dial # or wait until the timer decides that it's
not going to get any more digits and then routes the call. Is there any way
to set the routing table so that it knows that 5 will only be followed by 2
digits?

TIA

Liam

What you're describing sounds like a function of the handsets, not Asterisk.
What type of handsets are you using? How are they connected?

Are you sure it's not your phone that's putting the delay in? A lot
of them either have a built-in delay, or a separate "send" button...

Or are you using an ATA with analogue phone, or a TDM card with FXS
ports, etc.

More information needed..

You've probably got a good point, I've got a Starcomm UT1000, where it isn't
a problem because you "pre-dial" like with a cellphone, a Grandstream BT100
and a Sipura 841. You can put a dial plan into the Sipura on a "per line"
basis so it might be possible to sort it there. The BT100 doesn't seem to
have the facility for a dial plan. My son has X-lite, if you press the green
button you get dial tone but dialling afterwards doesn't connect at all.
However if you pre-dial and then press the green button you connect straight
away.

The name of this "feature" is Overlap Dialling, FYI.

Well unless definitions have changed in this new IP world I think that
you're incorrect. Overlap dialling would be where you have a number such as
01757XXXXXX and the exchange can resolve a routing choice based on the 01757
and does so even though it hasn't yet received the XXXXXX that it is
expecting.

Isn't that effectively what you're asking for?

The UT1000 has a "green" send button, so dial the number, then push
"send". As does the BT100. However, the BT100 can be put in a mode
where it will present the number to the PBX each time you push a digit,
effectively asking "is this a valid number" and if the PBX says no,
the phone waits for another digit... The default time-out on the BT100
is 4 seconds.

These are configurable on the BT100 web interface - to change the
time-out, look for the "No Key Entry timeout" (it's 4 by default), and
to make it present the number on each digit, look for the "Early Dial"
setting which is off by default. (On the advanced settings page)

I've no idea how the Sipura works, but I've got both UT1000 and BT100
phones, although I have to say that I'd never use them in anything
other than a "domestic" setting..

For the most part, with SIP/Soft phones, you need to think the same way
as you do with mobiles - dial then numner into the phone, then get the
phone to present the number to the PBX - usually via a "send" or
"green button", so dial then send, not the other way round.

Thanks. I changed it but the asterisk doesn't seem to support "early dial",
well at least not in the "off the shelf" Trixbox variant that I've got. I
don't know enough about asterisk to delve into it so I'll probably leave
things as they are.

No, not really. From the other replies to the post it's a moot point because
it seems that generally the phone sends all the digits at once, either after
an elapsed time, a # or by pressing a send button.

I was assuming that the digits were sent one at a time, in which case I
wanted to set the switch to recognise that after it saw a 5 it should expect
2 more digits then route immediately because it didn't need to wait for
more. It's not overlap dialling because it's not waiting for any digits to
forward.
