Hello MikeM,
Thanks for all your support and help. Well I have changed back the configuration back to the following. But the problem is: as soon as the call hit the gateway, it drops. If 7 calls are sent, only 1 or 2 becomes active.
config pstntg 1# pprriinntt
PSTN Trunk Group: 1
Name = PstnPassThrough1
Pass Through = yes(1)
PT Trunk ID = 0
Provide Call Progress Tone = no(0)
Busyout = no(0)
Hunt Algorithm = ascending-round-robin(2)
Modem Calls = No(0)
Direction = outgoing(1)
DN Used = public
End Of Dial = yes(1)
End Of Dial Digit = #
Add End of Dial Digit = no(0)
Ivr Type = None
CID = From Interface(0)
External Routing Request = no(0)
Auto Switch Enable = no(0)
Forced IP Routing # = none
Trunk ID(Account Code) = none
Trunk ID Delivery = none
2 Stage Dial = No
Translate Inbound Caller ID = no(0)
Relay Caller ID = yes(1)
IP Extension = no(0)
Maximum LAM Calls Allowed = 7
LAM: Index Pattern Replacement NumberType
Cas Signaling Type = loop start(1)
Cas Orientation = user(0)
Dial Tone Detect = yes(1)
Dial Delay Timeout = 1000

Flash-Hook Signaling = no(0)

Caller Id Detection = no(0)
dtmf-ontime = 100
dtmf-offtime = 100
Channel:
unit# 1 line# 2: 1,2,4,5,6,7,8
Thanks in advance.
