Unwanted entries created in dialplan, how to get rid of it?

Hello,

When I call “dialplan reload” I can see the following lines:

== Parsing ‘/etc/asterisk/extensions.conf’: == Found
– Registered extension context ‘default’ (0x8a72410) in local table 0x8a679d0; registrar: pbx_config
– Added extension ‘_1XX’ priority 1 to default (0x8a72410)
.
.
.
== Parsing ‘/etc/asterisk/users.conf’: == Found
– Added extension ‘100’ priority -1 to default (0xb731b4e8)
– Added extension ‘100’ priority 1 to default (0xb731b4e8)
– Added extension ‘101’ priority -1 to default (0xb731b4e8)
– Added extension ‘101’ priority 1 to default (0xb731b4e8)

That result in a dialplan that look like that:
[ Context ‘default’ created by ‘pbx_config’ ]
‘100’ => hint: SIP/100&IAX2/100 [pbx_config]
1. Dial(${HINT}) [pbx_config]
’_1XX’ => 1. Playback(digits/4) [pbx_config]

I don’t want those 2 first line to be there only the _1XX. How do I get rid of it? Why it is added to the dial plan automatically?

extention.conf look like this:
[default]
exten => _1XX,1,Playback(digits/4)

users.cong look like this:
[100]
username = 100
transfer = yes
mailbox = 100
call-limit = 100
type = peer
fullname = Polycom
registersip = no
host = dynamic
callgroup = 1
type = peer
context = default
cid_number = 100
hasvoicemail = no
threewaycalling = no
hasdirectory = no
callwaiting = no
hasmanager = no
hasagent = no
hassip = yes
hasiax = no
secret = 100
nat = yes
canreinvite = no
dtmfmode = rfc2833
insecure = no
pickupgroup = 1
autoprov = no
macaddress =
linenumber = 1
LINEKEYS = 1
disallow = all
allow = ulaw,gsm

Thanks,
