Call not going out of asterisk to other different server

Hi,

This is my first request to the asterisk forum, I do not even know if this is the correct place to ask this so please help me anyhow either with the solution or redirect me to correct place.

Issue:

X-lite clients regristered to my asterisk can call to and fro each other fine.

X-lite clients registered to an Adobe media gateway which is registered with asterisk server, can call in the asterisk x-lite clients successfully.

But when i try to call from x-lite of asterisk to x-lite of adobe media gateway then the call fails to establish.
777 is my x-lite registered at adobe media gateway which is 201
6002 is my x-lite at asterisk server
The asterisk log console reads:
Using SIP RTP CoS mark 5
–Executing[777@callingin:1] Dial(“SIP/6002/000000004”, "SIP/201/777,30) in new stack
==Using SIP RTP CoS mark 5
–Called SIP/201/777
[2014-07-08 07:07:30] Warning[2070][C-00000002]: chan_sip.c:22991 handle_request_invite: Received response: “Forbidden” from “6002” sip:6002@192.168.17.12;tag=as13f1c908’
== Everyone is busy/congested at this time (1:0/0/1)

And the call does not connect. however the incoming calls from adobe media gateway clients to asterisk clients work successfully.

The media server doesn’t want to talk to you. Asterisk is simply reporting the error message from the media server.

The correct forum was Asterisk Support.

Hi David, you are right this was an authentication issue. But still i was wondering why it is able to receive a call successfully but cannot call outside. Anyways, thanks David

You probably have allowguest=yes, which is usually a bad idea.
