[asterisk-users] Asterisk 1.2.12 - Can NOT make call out / Asterisk terminate

[Joseph]

I just upgraded to Asterisk 1.2.12 from 1.0.1 and it seems to me
Asterisk 1.2 is not ready for PRIME TIME.

I have three Sipura units registered with Asterisk 1.2.12; registration
goes through just fine but I can not make calls out:

Got SIP response 503 "Service Unavailable" back from 10.0.0.102
    -- SIP/pstn-1270-0819db50 is circuit-busy
  == Everyone is busy/congested at this time (1:0/1/0)
    -- Executing Hangup("SIP/11-08198610", "") in new stack

In addition Asterisk quits every time I try to make a call?
It just terminates.
