Wishes to all…
My problem is that, I installed asterisk and addons. Configured the extensions as well. But in the asterisk-log showing that
chan_sip.c: Registration from ‘sip:3007@xx8.xx3.xx0.x4’ failed for ‘xx2.xx6.xx4.xx2’ - Wrong password.
Sip.conf
[3007]
; Polycom Sound Point 600
type=friend
secret=xxxvx
record_out=Always
record_in=Always
nat=1 ; we assume clients are behind NAT
host=dynamic
vmexten=199 ; and have dynamic IP address
reinvite=no ; if so, we need to make them
canreinvite=no ; always go through Asterisk
qualify=3000
dtmfmode=rfc2833
;call-limit=1
callerid=“5007” <5007>
disallow=all
allow=ulaw
allow=g729
context=from-agents3k ; use a context that exists 
progressinband=no
Extension.conf

include => from-agents3k
[from-agents3k]
include => default

exten => _3XXX,n,SetCDRUserField(${MONITOR_FILENAME})
exten => _3XXX,n,Queue(testq,10)
;exten => _3XXX,105,Busy()
exten => t,1,Busy()
Where is the mistake? Pls help…
