Hi striker.
Thanks for your reply.

I'm using a SIP registration type for the inbound call.
I have an OpenVox GSM gateway connected to my GoAutodial server.

Here is my inbound carrier setup:
[Account entry]
host=192.168.10.12
disallow=all
allow=gsm
allow=ulaw
type=friend
insecure=very
dtmfmode=rfc2833
context=trunkinbound
qualify=yes
nat=yes

[dialplan entry]
exten =>_4575527172.,1,AGI
exten =>_4575527172.,2,Dial(SIP/${EXTEN:10}@001,,tTo)
exten =>_4575527172.,3,Hangup

Thank for your help....

try this and post your cli log

[Account entry]
host=192.168.10.12
fromdomain=192.168.10.12
disallow=all
allow=gsm
allow=ulaw

On another side, on my GSM gateway, in the call routing rules (you can see it on the picture linked), when i specify an arbitrary Caller ID number, the inbound call can pass but in the agent web client of GoAutodial, the phone number of the caller is write in the field "comments" rather in the field "phone"; which distorts the inbound call report and the name of the recordings files.
Hope you can help me more.
Thanks

share me the make and model no of your gsm gateway, i can check the manual for the same.

meanwile try this

go to vi /etc/asterisk/sip.conf

set
allowguest=yes

and reload the asterisk, then try the inbound call.

Hi Striker.
Here is the information about my gsm gateway:
Make: OpenVox
Model: VS-GW1600-20G

In my sip.conf, i have had allowguest=yes.
I have kept the carrier setup that you have suggested above, reloaded and tried inbound call. Unfortunately i get the same error.

Thanks for your help.
