[asterisk-users] libpri and zaptel to disable early B3

[King Ho]

Hi,

I am using Asterisk 1.2.14 with zaptel 1.2.12 and  libpri 1.2.4. 

When we make a call to an unallocated number, the phone company will play a 
recording saying it is unallocated and then send us the PRI cause 1. Is
there any way 
to disable the recording and have the phone company send us the cause code 
immediately upon determining that the number is unallocated?


Thanks in advance.

Best Regards,

King
