match the terminating number, there's no SINGLE fixed pattern for the
dialcodes. so how do you know how many digits of the term number to match
against the dialcode? you dont. you have to match the dialcodes against
the termnumbers then order by lenght of dialcode (matched) and take the first
record as the most accurate. (most digits).....</span></font><o:p></o:p></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

task of<br>
parsing the country code and city codes from a dialed number in the<br>
CDRs?<br>
<br>
I know that there is almost never a case where a concatenated country <br>
and city code could overlap with another country code, but what about<br>
city codes and local numbers? Is it possible for a concatenated city<br>
code and local number to match another city code in the same country?<br>
<br>
I already have the table of country and city codes built.<br>
<br>
Are there holes in this theory;<br>
<br>
1. Starting after the international dialing code, find the longest match<br>
for country code.<br>
2. Starting after the country code from step 1, find the longest match <br>
for city code within that countries table of city codes.<br>
3. The rest is the local number.<br>
<br>
Are there known exceptions?<br>
<br>
Am I reinventing the wheel rather than finding the right already<br>
existing resource? <br>
