[Asterisk-Users] IAX -> IAX -> SIP problems

[Matthew Boehm]

The setup:

 Inc SIP Call -> Asterisk 1 -- IAX --> Asterisk 2 -- SIP --> phone (3044)

Asterisk 1 shows the following: (1.0.3)

    -- Executing Goto("SIP/XX.XX.XX.XX-0819f590", "cytel-internal|3044|1")
in new stack
    -- Goto (cytel-internal,3044,1)
    -- Executing Dial("SIP/XX.XX.XX.XX-0819f590",
"IAX2/asterisk-alpha:asterisk at dev-asterisk/3044|30") in new stack
    -- Called asterisk-alpha:asterisk at dev-asterisk/3044
    -- Call accepted by XX.XX.XX.XX (format ulaw)
    -- Format for call is ulaw
    -- Hungup 'IAX2/devasterisk/1'

Asterisk 2 shows the following: (CVS-HEAD)

    -- Registered SIP '3044' at XX.XX.XX.XX port 1911 expires 3600
    -- Saved useragent "CSCO/7" for peer 3044
    -- Accepting AUTHENTICATED call from XX.XX.XX.XX, requested format = 4,
actual format = 4
    -- Executing Dial("IAX2/asterisk-alpha at asterisk-alpha/2", "SIP/3044,30")
Dec 29 08:36:09 WARNING[1496]: chan_sip.c:1351 create_addr: No such host:
3044,30
Dec 29 08:36:09 NOTICE[1496]: app_dial.c:803 dial_exec: Unable to create
channel of type 'SIP' (cause 3)
  == Everyone is busy/congested at this time (1:0/1/0)
    -- Hungup 'IAX2/asterisk-alpha at asterisk-alpha/2'

So how can Asterisk2 say 'no such host' when it just registered 3044
30seconds before this call came in? I'm not using any RealTime stuff
anywhere.

3044 is defined:
[3044]
md5secret=d2756499745e254f52a224713f1a7d91
type=friend
host=dynamic
nat=yes
canreinvite=yes
disallow=g729
context=cytel-internal

any ideas? Thanks,
Matthew
