Hi, 

I'm sorry for cross-posting this (from 
http://forums.digium.com/viewtopic.php?t=64280), but I havn't got any replies 
in the forum.. 

........ 


When I dial out from my Asterisk 1.4.19 installation on Debian (three SIP 
hardphones on a LAN, and an IAX2 connection over DSL to a commercial trunk) I 
get this error on the console: 


-- Executing [EMAIL PROTECTED]:1] Set("SIP/21-081ceea8", 
"CALLERID(all)=nnnnnnnnnnnn <88821268>") in new stack 
-- Executing [EMAIL PROTECTED]:2] Dial("SIP/21-081ceea8", 
"IAX2/88821268/40618405|30|r") in new stack 
[Sep 11 12:05:58] WARNING[7098]: app_dial.c:1202 dial_exec_full: Unable to 
create channel of type 'IAX2' (cause 3 - No route to destination) 
== Everyone is busy/congested at this time (1:0/0/1) 
-- Executing [EMAIL PROTECTED]:3] Congestion("SIP/21-081ceea8", "") in new 
stack 
== Spawn extension (default, 40618405, 3) exited non-zero on 'SIP/21-081ceea8' 


I can't see any traffic on the wire using ngrep, and the registry looks good: 

filserver*CLI> iax2 show registry 
Host dnsmgr Username Perceived Refresh State 
85.nnn.nnn.83:4569 N 88821268 85.nnn.nn.197:10000 60 Registered 
85.nnn.nnn.82:4569 N 88821268 85.nnn.nn.197:10002 60 Registered 


I can see traffic with ngrep while registering, and every 60 seconds after 
that. 

That "no route to destination" error is causing my hair to thin, and my trunk 
provider tells me that it's "usually something else", and that the errormessage 
is not that descriptive. 

What can I do to get more/better debugging info? I can't figure out what's 
wrong. 

Thanks!
