Cause: 3 Cause-txt: No route to destination

Hello
I am facing the following problem
I am trying to setup a fake IAX outbound route with the following entry in the
iax.conf file

[faketelco]
type=peer
context=faketelco

and added the following to extensions.conf

[faketelco]
exten => s,1,NoOp(This route is working)

when I dial
IAX2/faketelco/8888888888
for example,

I get the following error

Sep 2 19:07:39 NOTICE[29822]: channel.c:2413 __ast_request_and_dial: Unable to request channel IAX2/faketelco/8888888888 Cause: 3 Cause-txt: No route to destination

any help is really appreciated

thanks
