witch context are the inside/outside accounts configured to use

type = endpoint
transport = transport-udp-nat
context = in-out
disallow = all
allow = ulaw
from_user = 338929_test
auth = voipms
outbound_auth = voipms

your voipms account can only call out
that should only point to a context that can reach you internal phones

That is dangerously insecure! Incoming external calls, which aren’t authenticated (if you are trying to authenticate, that will be enough to break incoming calls - please stop feeding us your configuration in dribs and drabs; we need it all) - are an invitation to toll fraud. demo is unreachable for incoming calls. There is no information to say whether anything is reachable from local devices.

You will need a type=identify, or is that another drib or drab.

As you have no aors, you won’t be able to make outgoing calls.

You incoming context will answer and then immediately hang up as a result of falling off the end of the dialplan.

Please don’t start multiple threads for what is basically the same problem (initial configuration).

thanks. I follow the documentation provided by

Do you have something better to suggest ?

I guess they assume you know how to use contexts. The inbound one is incomplete. I guess they assume that that is obvious, and all they are really doing is showing you how to match the “DID”. The outbound being included in the context for is still dangerous. Unfortunately ITSP’s really don’t put much thought into these sample configurations; most of the chan_sip ones are poorly done.

You don’t need the 10000@ in the contact URI.
