 Sipura 3000 PSTN gets disconnected between each ringing
I've been searching for a post that should handle this problem but I'm not able to find the answer.
The trouble:
I've got a SPA3k ( latest firmware ) connected to my Asterisk ( 1.2.4 ) box. When there is incoming calls on the FXO I can se the ringing on the Asterisk console ie.
-- Executing GotoIf("SIP/asterisk-85d0", "1?2:3") in new stack
-- Goto (default,99,2)
-- Executing Set("SIP/asterisk-85d0", "CALLERID(num)=spa3000out") in new stack
-- Executing Dial("SIP/asterisk-85d0", "SIP/analog") in new stack
-- Called analog
-- SIP/analog-ed8a is ringing
== Spawn extension (default, 99, 3) exited non-zero on 'SIP/asterisk-85d0'
-- Executing Hangup("SIP/asterisk-85d0", "") in new stack
The problem is that for each signal a new log entry as above is issued and if I try to answer the call I must pick it up in the right moment of time, otherwise I just get a dialtone.
What have I missed???
EDIT:
The SIP/analog <99> is the FXS on SPA3k | 
Linear Mode
