asterisk users - Nov 2007 - Asterisk direct dialing

Hi,
     I am using Asterisk 1.2.24, I have written my dialplan to land
with an IVR with the same time if the customer knows the parties
extensions they can dial directly, but what happens is sometimes its
working and sometime its not working.
My extensions.conf as follows,

[incoming]
exten => 052477302,1,Wait(2)
exten => 052477302,2,NoOp(${CALLERIDNUM})
exten => 052477302,3,Goto(from-internal,s,1)

[from-internal]
exten => s,1,Answer()
exten => s,2,Background(welcome_pride5)
exten => 501,1,Dial(Zap/1)
exten => 502,1,Dial(Zap/2)
exten => 503,1,Dial(Zap/3)
exten => 504,1,Dial(Zap/4)
exten => 505,1,Dial(Zap/5)

 I dont know what could be the reason. Is there any other way that i can use.

Thank you, with regards,
Gopal,
