Hi Gary,<br><br>I think its a good idea to get 10 digits from the LEC, then you alway have more numbers to work with. At that point you could take more than 3 digits as significant and process them through a translation pattern to get them to the extension you want.
<br><br>For example, if the called number from LEC is <font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">XXX-593-3183, take 4 digits as significant and have a 3XXX translation pattern intercept the calls from your gateway and pass them to the correct partition/phone. You could have a 4XXX pattern catch calls to
</span></font><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">593-4183 etc. If you still run into problems you could take more sig digits and make the pattern more specific to the telephon exchange or something.
<br><br>Is there a requirement that you can only have significant digits set to 3?<br><br>Hope that helps/makes sense on monday morning.<br></span></font><br><div><span class="gmail_quote">On 9/17/06, <b class="gmail_sendername">

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I'm trying to determine a "best practices"
when setting up inbound DID's, extensions, etc. Let me explain:</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">In most situations I've been involved in, I've used
the last 4 digits of a DID as someone's extension. I make sure the LEC sends
10 digit's, and I do a significant digits of 4 on the gateway. This has always
worked well, and is easy to configure. However, in a recent install, this customer
was using 3 digit extensions, so I again had the LEC send 10 digits, and I made
the gateway significant digits of 3. Again, this worked, but the problem was that
I started running into to many situations where I had duplicate 3 digits. For example,
a DID might be 593-3183, so the phone extension was 183. But I also had a existing
fax line number that was 444-4183. As you can see, the last 3 digits are the same.
I could not make a translation pattern of 444183 because the gateway was only sending
3 digits. I ended up having the LEC forward the 4444183 to one of the DID ranges,
and then gave the fax the number from that range, but that is not what I want to
do in the future. </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I guess what I want to know is what is the "best practice"
going forward? Is it a good idea to have the LEC send 10 digits, and if so, what
should I set on the gateway for significant digit's, and how should I handle
my internal phones that are using the last four digits of the DID as their extension?
I've read a document on using translation patterns to prefix digits, etc,
but I'm not sure if that is the directions I should go. </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Can someone offer advice on this, and perhaps provide an example
of how to do this with both a 4 digit example, and a 3 digit example? I really want
to have more control over the lines, and not have to worry much about duplicate
numbers or having the LEC getting involved.</span></font></p>
