hi all:<br>
<br>
I'm trying to limit each registered user's active calls, so<br>
if that particular registered user pass the limit, FS stops sending any<br>
new incoming call to it and it can't make any new calls.<br>
<br>
I looked into 'limit' api, the counter increment everytime a<br>
call FS receives, regardless of which user it is for, and counter doesnt<br>
reset itself after the call is finished.<br></blockquote><div><br></div><div>I presume you mean the limit "dialplan app" and not API. In any case, if you have the default configs then locate the Local_Extension in conf/dialplan/default.xml. Add this line right after the condition:</div>

Note that you can change the value in the limit's data argument. For example, this would cause a limit of 4 concurrent calls, sending the 5th call into "oops, too many calls" extension:</div>
<div><br></div><div><div><font face="'courier new', monospace"><action application="limit" data="hash ${domain} $1 4 handle_over_limit XML over_limit_actions"/></font></div>
</div><div><br></div><div>The limit application handles everything for you. Note that this only covers calls made *to* the extension. If you want to handle calls made *from* the extension you will need to add another limit app to the dialplan. Here's an example; put it right after the "global" extension in default.xml:</div>
<div><br></div><div><div><font face="'courier new', monospace"> <!-- set outound caller limit --> </font></div>
<div><font face="'courier new', monospace"> <extension name="set outbound limit" continue="true"> </font></div>
<div><font face="'courier new', monospace"> <condition field="destination_number" expression="^1?\d{7}" break="on-false"/> </font></div>
<div><font face="'courier new', monospace"> <condition field="caller_id_number" expression="^(10[01][0-9])"> </font></div>
<div><font face="'courier new', monospace"> <action application="limit" data="hash ${domain} $1 4 handle_over_limit XML over_limit_actions"/></font> </div>
<div><font face="'courier new', monospace"> <action application="log" data="INFO Added limit for caller $1"/> </font></div>
<div><font face="'courier new', monospace"> </condition> </font></div>
<div><font face="'courier new', monospace"> </extension> </font></div>
<div> </div></div><div>Again, save, press F6 or do reloadxml. Now when this person makes a call to a 7-digit number or does 1+ 7 or more digits, it will add to his limit totals. However, if he just calls another 4-digit extension on the system then it won't add to his limit. (Adjust this as you see fit.)</div>
<div><br></div><div>Let me know if this works for you (it worked for me in my little lab setting) and I will throw it up on the wiki and maybe add it to the cookbook.</div><div><br></div><div>-MC</div><div><br></div><div>
