Outgoing to draytel not working

I have registered asterisk with draytel.org in sip.conf. Have a sip.conf section and a simple outgoing_calls section in extensions.conf. Asterisk shows dialing in cli but doesn’t go through.

[mydrayteluser]
type=friend
canreinvite=no
secret=password
qualify=yes
host=dynamic
context=outgoing_calls
defaultuser=drayteluser
mailbox=dave

[outgoing_calls]
exten => _X.,1,Dial(SIP/${EXTEN}@draytel.org)

-- Executing [0xxxxxx@outgoing_calls:1] Dial("SIP/xxxxxxxx-00000000", "SIP/xxxxxxxxxx@draytel.org") in new stack == Using SIP RTP CoS mark 5 -- Called xxxxxx@draytel.org == Everyone is busy/congested at this time (1:0/0/1) -- Auto fallthrough, channel 'SIP/xxxxxxx-00000000' status is 'CHANUNAVAIL'

Any ideas?

What is the output of “sip show peers” and “sip show registry” commands in Asterisk CLI?

sip show peers Name/username Host Dyn Forcerport ACL Port Status xxxxxxx/xxxxxxx 192.168.1.3 D N 0 UNKNOWN dave/dave 192.168.1.3 D N 5060 OK (22 ms) 2 sip peers [Monitored: 1 online, 1 offline Unmonitored: 0 online, 0 offline]

sip show registry Host dnsmgr Username Refresh State Reg.Time draytel.org:5060 N xxxxxxx 105 Registered Wed, 05 Jan 2011 00:08:23 1 SIP registrations.

Any ideas?

Please change the following definition of SIP friend:

type = peer
host = ip_of_draytel_server
