[Asterisk-Users] Unable to dial certain calls

[JP Russell]

To begin with, I am new to both asterisk and VOIP and although I've  
gotten pretty far with my Asterisk setup and have two different sip  
accounts working fine for outgoing calls I am having trouble with one  
issue.

My problem is that I have another provider who uses IAX2 that I wish  
to use for calling various countries, including local (The  
Netherlands) calls and calls to the US to name two.  I am able to  
call local numbers without a problem through this provider with  
Asterisk, but calling US numbers is not working.

I CAN call the same US numbers with the service by using a direct  
connection from a softphone for example.

The entries that show up in the log after failed attempts to call the  
US are:

Jul 11 20:04:04 WARNING[25225728]: File channel.c, Line 1851  
(ast_channel_make_compatible): No path to translate from SIP/2203-2929 
(4) to IAX2[vbx]/1(16)
Jul 11 20:04:04 WARNING[25225728]: File app_dial.c, Line 672  
(dial_exec): Had to drop call because I couldn't make SIP/2203-2929  
compatible with IAX2[vbx]/1

I don't see anything suspicious entries in the CLI logging with IAX2  
debugging on.  Searching the archives and google didn't turn up a  
solution to this or even point me in the right direction I'm afraid.

Anyone have any idea on what my problem is or I can go for this issue?
