[asterisk-users] A matter of context

[Eddie Mikell]

All:

I've starting building an asterisk system for our company, which has 
about 60 users.  I am new to asterisk, so thank you for your patience.

I've stripped the sip.conf and the extensions.conf down to the bare minimum:

Here is my extensions.conf file

[globals]

[general]
autofallthrough=no

[default]

[fromprovider]
exten => YYYYYYYYYY,1,Dial(SIP/151,20)

[phones]
exten => 150,1,Dial(SIP/150)
exten => 151,1,Dial(SIP/151)
exten => _X.,1,DIAL(SIP/${EXTEN}@xx.xxxxxx.net)

and the matching sip.conf:

[general]
port=5060
bindaddr=0.0.0.0 ;10.8.0.34
srvlookup=yes
disallow=all  ;read somewhere you have to disallow everything first
allow=ulaw
allow=alaw
allow=gsm
dtmfmode=rfc2833  ;; allows use of push buttons on grandstream
nat=no
externip=64.4.127.106
localnet=10.0.0.0/255.0.0.0
canreinvite=no

;; register sip service
;
;register => YYYYYYYYY:xxxxxxx:4xxxxxxxxxxx at ia.ntelos.net/YYYYYYYYYY
; This register statement works also.
;
register => YYYYYYYYYY:xxxxxxxxxxx:YYYYYYYYYY at ia.ntelos.net
;

[151]  ; define extension number for grandstreams
type=friend
context=phones
username=eddie
host=dynamic

[150]
type=friend
context=phones
username=regis
host=dynamic


; define sip service
[xx.xxxxx.net]
type                = peer
username        = YYYYYYYYYY
fromuser        = YYYYYYYYYY
user            = phone
host            = xx.xxxxx.net
fromdomain      = xx.xxxxx.net
outboundproxy   = xxxx.xxxxx.net
secret          = secret
context         = fromprovider


I can make outgoing phones ok.

Here's the problem.  When I make an incoming phone call, I get a sip 
error message stating extension not found.

If I comment out the [fromprovider] context, and leave exten => 
YYYYYYYYYY,1,Dial(SIP/151,20) in the
default context, everything works fine.

Why do the incoming phone calls work ok when defined in the default 
context and not in the fromprovider context.

I hope that is clear.

Thanks for any help and tips.  And thanks for everything I have gleaned 
from others who have answered previous "newbie" questions.
