[asterisk-users] Grandstream GXV-3000

[hin lee]

I am trying to set up a Grandstream GXV-3000 Video
phone to Asterisk ver 1.2.21.1.  The problem I'm
having is that it can call other SIP phones, but not
vice versa.  Can someone tell me where is the problem?
TIA!

Here's part of my configurations:

----------
sip.conf
----------
; 113 is the Grandstream phone
[113]
type=friend
username=113
secret=secret
context=default
dtmfmode = rfc2833
host = dynamic
qualify = yes
allow = h263
video=yes
videosupport=yes

; 112 is the X-Lite phone
[112]
type=friend
host=dynamic
user=112
username=112
secret=secret
allow=all
nat=no
 
-------------
extensions.conf
-------------
exten => 112,1,Dial(SIP/112)
exten => 112,2,Playback(vm-nobodyavail)
exten => 112,102,Playback(tt-allbusy)
exten => 112,103,Voicemail(b112 at default)

exten => 113,1,Dail(SIP/113)
exten => 113,2,Playback(vm-nobodyavail)
exten => 113,102,Playback(tt-allbusy)
exten => 113,103,Voicemail(b113 at default)
