trunk from Trixbox to Voxalot

[serje]

Hi!
I have problem - I cannot establish trunk from my Trixbox to Voxalot where I registered.
my peer details are:

allow=alaw&ulaw&gsm
context=from-trunk
disallow=all
host=eu.voxalot.com
secret=XXXXXXXXX
type=peer
username=YYYYYY

and my register string is YYYYYY:XXXXXXXXX@eu.voxalot.com

so at outbound routes I point 8. and 00. to Voxalot trunk
so when I call 00xxxxxxx or 8xxxxxx I hear " We are sorry, the number you are called couldnot be connected" :0((((((
at asterisk console I see the nex lines:
...
-- Called Voxalot/8(number I called)
-- SIP/Voxalot-08686608 answered SIP/2001-086224a0
-- Attempting native bridge of SIP/2001-086224a0 and SIP/Voxalot-08686608
== Spawn extension (macro-dialout-trunk, s, 20) exited non-zero on 'SIP/2001-086224a0' in macro 'dialout-trunk'
== Spawn extension (macro-dialout-trunk, s, 20) exited non-zero on 'SIP/2001-086224a0'
...

where am I wrong? how can I solve this problem?
please, help
