[asterisk-users] GSM gateway and FXO ATA

[Tomislav Parčina]

Hi list!

I'm trying to connect Analog GSM gateway (2N Ateus) with Asterisk 1.2.5 over Grandstream HT488 ATA. I have plugged gateway to FXO port of ATA. Incoming calls work the way I call GSM number and then I get DISA to call inside company. Outgoing call work well when I call VoIP number of ATA which calls gateway and then I dial number I wish to call over gateway. As I said, it works fine.

Now I would like to dial ATA_number+number_I_wish_to_call so that I don't have to dial twice when I'm trying to establish outgoing call from company thru gateway.

I have tried this but it doesn't work well.

; to dial outside thru GSM gateway
exten => _456.,1,Dial(SIP/${EXTEN},30,tTD(${EXTEN:3}))
exten => _456.,n,Hangup 

This is what I see on CLI:

    -- Executing Dial("SIP/577-104c", "SIP/4560989970434|30|tTD(248)") in new stack
  == Everyone is busy/congested at this time (1:0/0/1)
    -- Executing Hangup("SIP/577-104c", "") in new stack
  == Spawn extension (sip, 4560989970434, 2) exited non-zero on 'SIP/577-104c'

Why asterisk thinks that gateway is busy when it's not?
