In your sip.conf, each DID probably has its own [section]  either
type=friend or type=user and peer.  Within this [section] you define
the context=mainmenu for example.  We can tell each of these DIDs to
go to a different context within our dialplan.  At this point we can
then make each line do something different, such as ring a different
phone.  We could have one general purpose number to go to the
autoattendent, and the other lines could ring a phone directly.

I do this within' my iax.conf, but it should be similar for your
sip.conf.  You'll just have to look at either sip.conf samples, or
perhaps it'll seem self evident once you look at your own sip.conf.

Anyways, here's what I do for two incoming DIDs from a VoIP provider.

/etc/asterisk/iax.conf

[7830]
type=friend
host=asterisk
username=iax-user1
secret=password1
context=mainmenu
trunk=yes
disallow=all
allow=ulaw

[7831]
type=friend
host=asterisk
username=iax-user2
secret=password2
context=7831-incoming
trunk=yes

Then within your extensions.conf, you could do something like this...

/etc/asterisk/extensions.conf

[mainmenu]
;include => default    (*btw: you probably shouldn't do this*)
exten => s,1,Answer
exten => s,2,Background(/var/lib/asterisk/sounds/initial_greeting)
exten => 5,1,Directory(default)
exten => fax,1,Dial(SIP/6204,20)
exten => t,1,Goto(mainmenu,s,1)
exten => i,1,Playback(invalid)

[7831-incoming]
exten => s,1,Answer
exten => s,2,Dial(SIP/100)
exten => s,3,Voicemail(u100)
exten => s,4,Hangup
exten => s,103,Voicemail(b100)
exten => s,104,Hangup

Hope this helps,
Leif Madsen.
