asterisk users - Jul 2005 - Extensions will not go to voicemail

I have a remote installation that connects via IAX from my office pbx. 
When I call an extension on the remote pbx, after the dial period, the 
call is terminated. Nothing I do in configuration of that extension 
seems to matter:

    -- Executing NoOp("IAX2/netconcepts@nnn.nnn.nnn.nnn:4569-5",
""Dial
710"") in new stack
    -- Executing Dial("IAX2/netconcepts@nnn.nnn.nnn.nnn:4569-5", 
"SIP/710|30|tr") in new stack
    -- Called 710
    -- SIP/710-4841 is ringing
  == Spawn extension (office, 710, 2) exited non-zero on 
'IAX2/netconcepts@nnn.nnn.nnn.nnn:4569-5'
    -- Hungup 'IAX2/netconcepts@nnn.nnn.nnn.nnn:4569-5'

and the dialplan for that context is

[office]

exten => 710,1,NoOp("Dial 710")
exten => 710,2,Dial(SIP/710,30,tr)
exten => 710,3,Voicemail(u710)
exten => 710,103,Voicemail(b710)

Any ideas why I am not getting to the voicemail for that extension?

My guess would be that system placing the IAX2 call has a shorter 
timeout than this one, so this one never gets a chance to go to voicemail.

What does the CLI look like on the pbx that has exten=>710 defined?

If you do a 'sip show peers' on that remote pbx, is 710 in the list?

Is x710 on the same lan segment as the remote pbx? (If not, are there
any nat boxes or firewalls involved?)

Does a local call from some extension on that remote pbx to x710
on the same pbx work correctly with voicemail?
