[Asterisk-Users] Not able to establish IAX call

[Remco Barende]

Hi list!

I set up a dual server config as outlined in the excellent howto at 
voip-info.org by JR.

When I try to call an extension on the other server however the call is 
not getting through. This is what appears on the asterisk server that 
should forward the call to the remote server:

Oct 13 12:44:24 WARNING[-1246008400]: channel.c:1901 ast_request: No 
channel type registered for 'IAX'
Oct 13 12:44:24 NOTICE[-1246008400]: app_dial.c:742 dial_exec: Unable to 
create channel of type 'IAX'

At no place in the howto however there is any reference to setting a 
'channel type'

I omitted the port numbers from the howto because they seem to apply to 
IAX1 only which has been obsoleted.
