[Asterisk-Users] Iconnecthere connect problem

[rnc Info Lists]

I have an Asterisk box behind NAT and am trying to connect to Iconnecthere
as was indicated possible earlier.  Am getting the following on the
Asterisk console:

  -- Executing Dial("SIP/2001-12c8", "SIP/1706xxxxxxx at delta3") in new stack
    -- Called 1706xxxxxxx at delta3
  == No one is available to answer at this time


sip.conf is:
[delta3]
type=peer
username=xxxxxxxx
secret=xxxx
host=213.137.73.140

the extension.conf entry is:
exten =>_1706NXXXXXX,1,Dial,SIP/${EXTEN}@delta3

Am I missing something??
