Issue Description

he Customer recive from the PSTN VIA PRA trunk only the last three numbers 

Handling Process

1.After analyzing LMT wer found that the PSTN sned anly the last three number to the u1900 

for example if the called numver from outside is 654123 the PSTN send only 123 

2.So we mad prefix 1 and mad number change 1 and add to the called number 

but we the custoemr has big range of long numbers for example 645(123), 645(235).........645(935) so the solution to make 9 prefixes was not acceptable 

3.So we add the number 645 to the trunk by using these commands 

a.Show trunk group 

b.config modify trun group no X cldpredeal yes cldindex Y 

(x is the trunk group number ) (y s the number changed made to add 645 on the trunk)

Root Cause

The PSTN send only three numbrs from the called number 

Solution

add the number 645 to the trunk by using these commands 

a.Show trunk group 

b.config modify trun group no X cldpredeal yes cldindex Y 

(x is the trunk group number ) (y s the number changed made to add 645 on the trunk)
