[asterisk-users] Two lines for outgoing calls

[Dominik Zalewski]

Dear All,

I'm using Asterisk 1.4.16.2 with Zaptel 1.4.7 on Debian with kernel
2.6.18. 

I have two analog lines Zap/1 and Zap/2 as group 1 in zapata.conf. I'm
using below context for dialing out.

[outbound-local]
exten => _9XXX,1,Dial(Zap/g1/${EXTEN:1},30,tTr)
exten => _9XXXXX,1,Dial(Zap/g1/${EXTEN:1},30,tTr)
exten => _9ZXXXXXX,1,Dial(Zap/g1/${EXTEN:1},30,tTr)
exten => _9ZXXXXXXX,1,Dial(Zap/g1/${EXTEN:1},30,tTr)
exten => _90900XXXXX,1,Dial(Zap/g1/${EXTEN:1},30m,tTr)

When Zap/1 is busy and I try to call, it will use Zap/2 which is fine
but there is something wrong cause I hear one ring and then a weird
sound like a noise or something and then hangup. I have to reload zaptel
modules and then everything works fine for a while.

   -- Executing [9150 at from-internal:1] Dial("SIP/200-08221590",
"Zap/g1/150|30|tTr") in new stack
    -- Called g1/150
    -- Zap/2-1 answered SIP/200-08221590
    -- Hungup 'Zap/2-1'

I even thought that second fxo module is broken so I changed it. No
results.

Any ideas?

Thank you in advance,

Dominik
