Summary:                    After installing PBX, unable to make SIP to PSTN
calls most of the times
Description: 
I have a TDM 400 card installed in a system that has asterisk-1.4.
I connected one PBX line to TDM 400. 
one PSTN line connected PBX.

Now, when I call a mobile/land line number from SIP, most of the times
calls are not going.

Asterisk console shows that its sending DTMF digits. but calls are
notgoing.

my zapata.conf is ::

; Trunk groups are used for NFAS or GR-303 connections.
;
; Group: Defines a trunk group.
;        group => <trunkgroup>,<dchannel>[,<backup1>...]
;
;        trunkgroup  is the numerical trunk group to create
;        dchannel    is the zap channel which will have the
;                    d-channel for the trunk.
;        backup1     is an optional list of backup d-channels.
;
;trunkgroup => 1,24,48
;
; Spanmap: Associates a span with a trunk group
;        spanmap => <zapspan>,<trunkgroup>[,<logicalspan>]
;
;        zapspan     is the zap span number to associate
;        trunkgroup  is the trunkgroup (specified above) for the mapping
;        logicalspan is the logical span number within the trunk group to
use.
;                    if unspecified, no logical span number is used.
